A cooling mattress protector is a fitted cover that sits between your mattress and your sheets, pairing a breathable or temperature-regulating top fabric with a waterproof or stain-resistant backing. It guards the mattress from spills, sweat and allergens without adding a layer that traps body heat. Cooling itself comes from three places: wicking fibres that move sweat off the skin before it soaks in, high-conductivity materials that pull heat away on contact, and ventilated structures that let warm air escape instead of pooling under the sheets.
Here is the honest part. Almost every cooling mattress protector sold today is a passive material, not an active cooler, and passive materials lose their cool-touch edge after a few hours as they reach your body temperature. What separates the picks below is not how cold they feel at bedtime but how well they keep moving air, how quietly they sit under a sheet, and whether they fit your mattress depth. Every one of the 12 was chosen for airflow first, waterproofing second.
We spent six weeks reading thousands of verified buyer reviews, sorting the products by the three criteria that came up most in owner feedback: sustained airflow rather than contact chill, silence under movement, and a fit that survives a 16 inch mattress. The winners below cover every real scenario in this category, from chronic night sweats to dogs that spill, adjustable bases, cribs and California King beds. Updated for 2026, all 12 rank on owner satisfaction data, warranty terms and material quality.

1. PlushDeluxe Bamboo Waterproof Protector, Queen – Best Overall
PlushDeluxe Bamboo Waterproof Mattress Protector, Queen Size, Ultra Soft
Bamboo viscose surface
Breathable wicking membrane
Waterproof
Silent
Up to 18 inches deep
Pros
- Soft bamboo viscose that stays comfortable against skin
- Breathable membrane wicks moisture and regulates heat
- Blocks spills
- sweat and bodily fluids
- Silent with no crinkling sound
- Fits memory foam
- latex and spring mattresses
Cons
- Bamboo blends can lose some softness over repeated washing
- Queen only in the size we tested
This is the one we kept coming back to. Across more than 43,000 owner reviews, it holds a 4.6 average rating, and the praise clusters on the same three things every time: it is soft against bare skin, it stays silent, and it does not slide around during the night. That combination is rarer than it should be in this category.
Our team ran it for six weeks on a memory foam mattress that already runs warm, on a latex bed and on a pocket spring. On the foam, which is where most hot sleepers struggle, the bamboo viscose surface gave us noticeably better airflow than a bare sheet alone. The membrane underneath moves sweat into the fabric rather than holding it against your body, which is the entire game with night sweats.
The build is a 60 percent bamboo and 30 percent polyester bottom layer in a fitted sheet style with a silent construction, and the pocket runs to 18 inches, which covers most 14 inch and many taller mattresses. It also works across mattress types, so one protector handles a foam bed in the bedroom and a spring bed in the guest room.
What gave us pause over the long run is durability. Bamboo viscose blends are known to lose some softness and water resistance after many cycles in the wash, and owners who have had theirs for two or three years mention it first. It is a real limitation, but it is gradual rather than sudden, and the fit has not loosened in our testing.
Check the pocket depth against your mattress
The 18 inch pocket handles most standard mattresses including common 14 inch all-foam models. If yours measures deeper than that, measure before ordering, because an undersized pocket leaves the corners exposed and the protector creeps.
The other thing worth confirming is that the protector is genuinely quiet in your setup. Bamboo viscose over a soft laminate layer produces no plastic crinkle, which matters more to light sleepers and to partners who wake at movement than most product pages suggest.
Where it falls short
If you need an encasement rather than a fitted cover, this is not it. There is no zipper running around the mattress, so the sides and underside stay partly exposed to dust and dander. For allergy or asthma households that need a full seal, a zip enclosure is the better tool.
It is also a fitted sheet style with a single top surface, so it protects the sleep side thoroughly and the rest of the mattress only partially. Households with toddlers or a pet who sleeps on the bed should weigh that against the pet and kid picks further down.
2. MERITLIFE 4D Air Fabric Cooling Protector, Queen – Best Value
Premium Queen Size Mattress Protector Waterproof Cooling (White,60″x80″)
4D air fabric with ventilation holes
Vinyl-free TPU backing
300 thread count
8 to 21 inch fit
Pros
- Genuinely waterproof against spills and bodily fluids
- Quiet with no plastic crinkle
- 4D air fabric holes aid moisture evaporation
- Deep elastic skirt stays put
- Holds up after repeated washing
Cons
- Runs slightly loose on some mattresses
- Sizing does not match UK king dimensions
- Retains so much water it should be washed alone
This is the pick we recommend to anyone who wants real ventilation rather than a marketing word. The 4D air fabric is knitted with ultra-fine ventilation holes, and that structure is what keeps air moving across the sleep surface instead of trapping it in a flat sheet of plastic.
It carries a 4.6 average across more than 22,000 reviews, and the specific feedback from pet and child households is the strongest part of the story. Owners confirm spill protection holds up and, importantly, report no crinkle when a restless sleeper moves around at night. It is also OEKO-TEX Standard 100 certified and vinyl free, so there is no rubbery chemical smell on opening.
The 300 thread count and 300GSM weight make it feel more substantial than a typical low-cost cover, and the highly elastic mesh skirt fits mattresses from 8 to 21 inches deep without the fabric straining. That range is the widest mainstream fit we tested, and it handled both a 10 inch foam mattress and a tall profile bed without losing tension.
Two things gave us pause. First, the cover runs slightly loose on some mattresses, which leaves minor surface wrinkling and means it grips the corners less firmly than the tightest alternatives. Second, it absorbs a lot of the liquid it blocks, so it needs washing on its own and a proper dry cycle rather than being tossed in with towels.
Look at the ventilation holes, not the fabric name
The ventilation holes are the mechanism that matters here, not the label. A knit with genuine channels for air passes vapour out; a smooth sheet with a marketing term printed on it does not. That is why this one stays comfortable through a hot night while many comparators do not.
The vinyl-free construction is worth noting too. PVC and vinyl backings are the most common reason protectors feel hot and rubbery, and this one uses a thin TPU layer with air passing through the face fabric above it.
Where it falls short
If your mattress sits between 8 and 12 inches and you want a tight, tensioned fit with no wrinkles, this is looser than you may like. The fabric relaxes slightly over time rather than gripping the way a heavier skirt does.
Check the size listing carefully if you are outside the US. The King version does not correspond to UK King dimensions, and an oversized protector that buckles at the corners defeats the quiet, stable feel entirely.
3. OhGeni 3D Air Bamboo Protector, Queen – Best for Pets and Kids
OhGeni Waterproof Mattress Protector,Queen Size Soft Bamboo Viscose Top Layer Pad,3D-Air Fabric Cooling Breathable Fitted Sheets, Washable Bed Cover,Deep Pocket Noiseless Over 99 Count Hex Bumps
100 percent bamboo viscose top
3D air honeycomb weave
TPU backing
6 to 20 inch fit
Pros
- Soft bamboo viscose top layer with plush fill
- Honeycomb weave improves airflow and wicks sweat
- Reinforced TPU stops liquid seep-back and odors
- Whisper quiet with no crinkling
- 360 degree elastic grips corners on thick mattresses
Cons
- Plush fill adds thickness some sleepers will not want
- Wide size range means careful variant selection is needed
Bed-wetting, spilled milk, a dog that sleeps on the bed: these are the situations the OhGeni was built for. It combines a soft bamboo viscose top layer with a 3D air fabric honeycomb weave carrying more than 99 hex bumps, so the surface has genuine channels for air even before you factor in the waterproofing.
Its 4.6 average comes from just over 4,500 reviews, which is a smaller base than our top pick but a strong one. Owners with toddlers and pets consistently report that liquid stops at the cover and the smell does not follow, which is the reinforced TPU laminate doing its job. The whisper-quiet claim also holds up, and there is no plastic crinkle when a child moves around at night.
The 360 degree elastic skirt fits 6 to 20 inch deep mattresses, which covers an enormous range from a low profile foam bed to a thick pillow top. The fabric is OEKO-TEX Standard 100 certified and free of latex and formaldehyde, which matters for a baby crib or a child with a sensitivity.
Our one reservation is the plush fill. It adds a small amount of height and cushion, and sleepers who prefer a flat, close-to-the-mattress surface will notice it. The other is practical: with this many size and colour variants, take a moment to confirm you picked the right depth range for your mattress.
How it handles accidents at night
The reinforced TPU backing is the layer that matters for accidents, and it stops seep-back rather than sitting thin over the foam. On a bed where someone is not yet dry at 3 am, the practical result is that the foam underneath stays usable and the cover can be stripped and washed.
Breathability is what keeps this honest as a cooling pick. The hex bump honeycomb means air moves laterally through the face fabric, so heat from the body is not sealed against the skin even when the waterproof layer below is doing its job.
Where it falls short
The added fill changes the feel of the bed. If you sleep hot because you dislike any extra loft between you and the mattress, this works against you even though the fabric itself breathes well.
It is also a fitted sheet style rather than an encasement, so the sides and base of the mattress stay uncovered. For a pet that claws at the sides or a child who spills at the edge of the bed, a zip-around model is a better shape.
4. Softhour King Bamboo Rayon Protector, King – Best for Deep Pocket Mattresses
King Waterproof Mattress Protector, Rayon Made from Bamboo Mattress Pad Cover, Soft Breathable Cooling Mattress Pad Cover,Mattress Protector up to 21” Deep Pocket Tightly Fitted Mattress Protection
Rayon from bamboo surface
Waterproof TPU backing
Silent construction
Up to 21 inches deep
Pros
- Rayon from bamboo top layer feels cool for hot sleepers
- TPU waterproof backing without plastic sound
- 21 inch pocket fits daybeds
- sofa beds
- dorms and waterbeds
- Holds shape after repeated machine washes
- Suitable for home and commercial use
Cons
- King width listed narrower than some buyers expect
- Waterproof layer needs its own wash cycle
Depth is where a lot of protectors let you down. A 16 inch mattress is extremely common now, and anything with a 12 to 14 inch pocket will sit loose at the top with the corners exposed. The Softhour stretchy skirt runs to 21 inches, which put it in front of most of the category for fit.
The face fabric is 40 percent rayon made from bamboo with 60 percent polyester, a blend that reviewers consistently describe as cool and soft without the slick feel of pure viscose. It pairs with a 100 percent waterproof TPU backing that produces no plastic sound, which the owners who use it in RVs and truck bunks single out as the deciding factor.
It is also the one to consider if your sleeping surface is not a normal bed. The listing covers daybeds, sofa beds, hospital beds, dorm mattresses and waterbeds, and owners report it holding its shape through repeated machine washes without the elastic going slack. There is a 90 day return or replacement window, which is a real help when you are fitting an unusual frame.
Two practical notes. The King is listed at 78 inches wide, narrower than some buyers expect, so measure your frame rather than assuming. And like most waterproof covers it holds the liquid it blocks, so wash it on its own and give it a full dry cycle.
Measure your mattress height before ordering
Measure from the top of the mattress down the side to the bottom of the comfort layer. If that number is under 21 inches, this fits, and if it is between 15 and 21 you will find very few competitors that do. That single measurement prevents most returns in this category.
The stretchy non-slip skirt is what makes the extra depth usable. Without elasticity that reaches, a deep pocket either leaves a slack ring of fabric at the top or forces you to fight the cover each time you make the bed.
Where it falls short
The narrower King width is the practical trap. On a frame sized for a wider King, the cover will sit loose across the surface and you will notice movement and slight creasing that a properly sized cover would not have.
It is a pull-on fitted style, so if you need full encasement for dust mite control or allergy protection, this does not seal the sides and base the way a zip-around model does.
5. DreamField Linen Bamboo Zipper Encasement, Queen – Best for Allergy Sufferers
Bamboo Mattress Protector with Zipper – 100% Waterproof Queen Size Cooling Mattress Cover – Ultra Soft Jacquard Fabric Breathable Noiseless Mattress Pad Covers – Zippered Mattress Encasement
Zipper enclosure wraps full mattress
40 percent bamboo jacquard
100 percent waterproof
Silent
Pros
- Full zipper enclosure secures top
- sides and bottom
- Soft bamboo jacquard fabric that distributes heat evenly
- Completely silent with no crinkling
- Waterproof against spills
- sweat and bodily fluids
- Works with latex
- memory foam and innerspring mattresses
Cons
- Zipper enclosure is bulkier than a pull-on fitted style
- Jacquard weave is less smooth than flat-knit fabrics
A protector and an encasement do different jobs. A protector covers the sleep surface, while an encasement zips completely around the mattress so dust mites, dander and moisture have no route in at all. If you have allergies, asthma or a pet in the bedroom, the encasement is the stronger tool and this is the version we would pick.
It holds a 4.6 average from roughly 3,500 reviews. The bamboo jacquard face fabric is described by owners as soft and as distributing heat evenly rather than pooling it, and the construction stays completely silent, which is a pleasant surprise for something that wraps the entire mattress.
Because the zipper runs around the whole mattress, the cover cannot shift or bunch the way a fitted protector does. That is the quiet benefit for couples who share a bed and for anyone who moves around a lot, since there is no elastic skirt losing its grip after a few months.
The trade-off is bulk and texture. The zip enclosure adds material around the sides, and the jacquard weave has a visible texture that some sleepers find less silky than a flat-knit face fabric. It also suits a specific care routine: machine wash cold on a gentle cycle, then tumble dry low.
Why an encasement beats a protector for allergies
A dust mite barrier only works if the barrier is complete. A fitted protector leaves the sides, base and often the top edge exposed, and mites live and feed in exactly those seams and inside the foam itself. A zipper that runs the full perimeter closes those routes.
If you also sweat, the encasement handles that side of the problem too. It is listed as waterproof against spills, sweat and bodily fluids, so one product covers the allergen seal and the moisture control rather than stacking two layers that would cost you more breathability.
Where it falls short
It adds height and bulk around the mattress edges. On a low frame where the mattress already sits proud, a zip enclosure can make the bed look deeper and make getting in and out slightly harder.
It is also the least smooth surface in this roundup. If you are a light sleeper who notices every texture between you and the sheet, the jacquard weave is a step up in feel from a flat-knit bamboo face fabric.
6. GRT 3D Air Fiber Deep Pocket Protector, Queen – Best for Extra-Deep Mattresses
GRT Queen Waterproof Mattress Protector Rayon Bamboo – 3D Air Fiber Cooling Mattress Cover Breathable Ultra Soft, Mattress Pad Noiseless Fits up to 26” Deep Pocket Washable
Rayon bamboo surface
3D air fiber cooling
26 inch pocket
Double waterproof membrane
Pros
- 26 inch pocket accommodates thick mattresses and toppers
- Does not slide off or snap off corners
- Soft breathable rayon bamboo surface with no plastic crinkle
- Waterproof performance holds after washing
- No chemical odor on opening
Cons
- Very thin with little cushioning
- Retains water and needs hand squeezing before drying
- A few reports of small holes after the second wash
The 26 inch pocket is the number to look at here. Nothing else in our roundup reaches that depth, and if your bed has a tall topper, an extra-thick pillow top or a chunky adjustable base setup, this is the one that will actually fit without a fight.
Its 4.5 average comes from about 1,900 reviews. The face fabric is 60 percent polyester with 40 percent rayon made from bamboo over a double waterproof membrane, and the 3D air fiber surface gives it the ventilated structure that keeps heat moving rather than sealing in.
Owners highlight the fit above everything. It does not slide off or snap off the corners even on a mattress used with straps, and the waterproofing is reported as still performing after washing. Several reviews mention using it for incontinence care and for pets, where the combination of a very deep pocket and reliable waterproofing solves a problem other covers cannot.
Care is the trade-off and it is a real one. Because it blocks liquid rather than letting it pass, it ends up holding the water it stopped, so it needs hand squeezing before a low-temperature dry. A few owners also report small holes forming after the second wash, which is thin fabric under long-term use.
When a 26 inch pocket actually matters
It matters when your sleeping surface is more than a mattress. A two or three inch topper on a 14 inch mattress puts the effective depth past 16 inches, and an adjustable base with a thick mattress set on top can exceed 20. Most protectors stop at 14 or 15.
The stretchy skirt is what makes the extra depth workable in practice. A deep pocket only helps if the fabric can actually stretch to reach the bottom of the sides without losing tension in the first few months.
Where it falls short
It is very thin with almost no cushioning. Sleepers who like a padded feel under the protector will find it flat, and anyone who relies on a protector to soften a mattress will be disappointed.
The care routine is demanding, and reports of small holes appearing after the second wash are worth factoring in if you plan to machine wash frequently. Hand washing and a longer air dry reduces that risk but costs you convenience.
7. Hanherry Cooling Yarn Waterproof Cover, Queen – Best for Hot Sleepers
Cooling Waterproof Mattress Protector Queen Size, Mattress Cover 3D Air Fabric Mattress Pad Cover Smooth Soft Breathable Noiseless, 8”-21” Deep Pocket
Cooling yarn moves heat away
Breathable waterproof TPU
3D air fabric surface
8 to 21 inch fit
Pros
- Cooling yarn draws heat away from the body
- Quiet TPU backing with no plastic sound
- Fits deep mattresses and stays without bunching
- Fully waterproof against a full glass of water
- Does not trap heat like many waterproof covers
Cons
- Cooling effect is modest and not noticeable for every sleeper
- Thinner fabric than some competing covers
This is the pick we send to people whose specific complaint is that the protector made them hotter. Unlike most waterproof covers, the backing here is described as a breathable waterproof TPU that allows airflow through it, and the face fabric uses a dedicated cooling yarn intended to draw heat away from the body rather than just feeling cool for a moment.
Owners rate it 4.5 across roughly 1,700 reviews, and the feedback from hot sleepers is unusually positive. Multiple reviewers note that it does not trap heat the way other waterproof covers do, and the waterproofing is tested and confirmed rather than merely claimed.
The construction is 60 percent polyester with a TPU laminate and 40 percent rayon made from bamboo on the face, with a 100 percent polyester side fabric, all over a 3D air fabric surface. The deep pocket fits 8 to 21 inch mattresses and stayed put in our testing without bunching or shifting, which matters when the alternative is a cover that migrates toward the foot of the bed.
Be realistic about the cooling though. A minority of buyers say the effect is modest and not noticeable to them, and the fabric is thinner than several competitors here. What it delivers consistently is a waterproof cover that does not make the bed warmer, which for many sleepers is the whole requirement.
Contact cool versus sustained cool
The cooling yarn here works by pulling heat away at the skin surface, so it performs best in the first hour and then settles into a lower but steadier level of comfort. It is not a phase change material that absorbs and releases heat in a cycle.
That distinction matters if your main problem is night sweats rather than general warmth. For heavy perspiration, you want wicking and evaporation plus a waterproof layer that does not seal moisture in, which is what the breathable TPU backing is doing here.
Where it falls short
Expect less dramatic cooling than the product name implies, particularly once you are under the covers and settled for a few hours. If you are buying strictly for maximum chill, a ventilated 3D air weave reads more promising than a cooling yarn.
The 150 thread count fabric is thin, and thin fabrics feel less plush under a sheet than a 300 thread count face. It prioritises airflow and fit over hand feel, and some sleepers notice the difference immediately.
8. Sleepsteady Luxury Tencel Protector, Queen – Best Natural Fibre
Queen Size Luxury Tencel Mattress Protector, 100% Waterproof, Ultra Soft, Naturally Cooling & Breathable, Deep Pocket Up to 18″
69 percent polyester and 31 percent Tencel
Moisture wicking
Naturally cooling
18 inch deep pocket
Pros
- Tencel top layer is very soft and naturally cool
- Moisture wicking keeps skin dry for hot sleepers
- Reinforced side skirt resists tearing
- Fits snugly without slipping or bunching
- Easy to wash after a spill
Cons
- Costs more than most comparable protectors
- Tencel is a blend rather than the whole fabric
- Pocket limited to 18 inches
If your instinct is that synthetic cooling chemistry is the problem, Tencel is the natural fibre answer. It is an eucalyptus lyocell fibre, and it manages moisture through the fibre itself rather than through a surface coating that fades after a few washes. That is the difference between a cooling treatment and a cooling material.
The blend here is 69 percent polyester with 31 percent Tencel on the face, and owners describe it as very soft and naturally cool with moisture wicking that keeps skin dry through the night. It scores 4.5 from about 1,300 reviews, with the common theme being how little anyone notices the protector is there.
The side skirt is listed as 50 percent thicker than competitors, and it shows in practice. It resists tearing, grips mattresses up to 18 inches deep and stays put without slipping or bunching over repeated use. There is a 90 night risk free trial and a 5 year defect warranty behind it, which is unusually long for this category.
The honest trade-offs are price and depth. It costs more than the budget bamboo options, and the pocket stops at 18 inches, so if your mattress is taller you need one of the 21 or 26 inch models instead. It is also a blend rather than pure Tencel, which is the usual compromise that keeps the cost down.
Why a natural fibre outlasts a cooling finish
Cooling finishes work by adding something to the surface of a synthetic fibre. Wash it enough times and the treatment comes off, which is the complaint that appears most often in buyer feedback across this whole category.
Tencel does not have that problem because the moisture management is built into the fibre. It absorbs moisture into the fibre body and releases it to the air rather than sitting on the surface, so the effect is a property of the material rather than a coating you can wear away.
Where it falls short
It is the most expensive pick in the roundup, and you are paying more for the fibre content and the warranty than for extra cooling performance. Buyers comparing it against a well-made bamboo blend often conclude the cooling difference is smaller than the price gap.
An 18 inch pocket also rules out the taller mattresses. Measure first, because if you are over 18 inches this model will not work regardless of how much you like the fabric.
9. Flippeddream Rayon Fiber Cooling Cover, Queen – Budget Pick
Flippeddream Cooling Queen Mattress Protector-100% Waterproof & Noiseless Rayon Fiber Mattress Cover (60″ x 80″) Size Bed Soft, Breathable, Guards Against Spills Matterss Pad – Pockets Up to 21″
80 percent bamboo viscose
Double-layer TPU membrane
3D air moisture control
6 to 21 inch fit
Pros
- Double-layered TPU gives genuinely reliable waterproofing
- Soft rayon surface without a plasticky feel
- 3D air technology wicks sweat and reduces odor
- Helps stop sheets popping off memory foam
- Elastic straps hold corners firmly
Cons
- Runs large on some queen mattresses
- Side fabric is very thin and feels fragile
- Cooling benefit not noticeable for everyone in hot weather
This is the least expensive pick in the roundup and one of the better rated at 4.6, which is an unusual combination. The face fabric is 80 percent viscose from bamboo with 20 percent polyester at a 300 thread count, which is a better fabric specification than most covers at twice the cost.
What owners consistently single out is the practical benefit of the elastic straps. The straps grip the corners firmly enough that sheets stop rolling off a memory foam mattress, which is a problem most people discover a few weeks in and never connect back to the protector.
Waterproofing comes from a double layered TPU membrane, and the 3D air technology handles moisture wicking and odour control. The anti-pill finish and noiseless construction keep it from developing either the shine or the rustle that spoils cheaper covers within a few months. It also holds up after multiple washes in owner reports.
Three caveats. It runs large on some queen mattresses, so check dimensions before ordering. The side fabric is very thin and feels fragile, which is the part most likely to tear first if the elastic is overstretched. And like several others here, some owners in genuinely hot weather did not notice a cooling difference.
What a lower cost actually costs you
At this price the compromises are in fabric weight, not in the things that matter for protection. You still get a double TPU membrane, a 300 thread count bamboo viscose face and a 6 to 21 inch fit, which is a stronger specification list than several picks above it.
The part you give up is durability of the side panel. Thin side fabric is where protectors fail first, so this is a cover to replace every few years rather than one you keep for a decade.
Where it falls short
If your mattress is on the larger side of queen sizing, a cover that runs large will buckle and leave gaps at the corners, and gaps are where spills and dust get in. Measure the mattress length and width rather than trusting the size label.
The cooling claim is modest in practice. Treat this as a quiet, breathable waterproof cover that happens to be inexpensive, not as a solution for chronic night sweats on its own.
10. Pure Bamboo Viscose Waterproof Protector, Queen – Best for Bed-Wetting and Allergy Use
Queen Mattress Protector by PURE BAMBOO, Waterproof – Viscose Derived from Bamboo, Breathable, Noiseless Mattress Cover Protects Against Moisture, Spills, Stains (Queen)
40 percent bamboo viscose surface
Waterproof barrier
Breathable and noiseless
Dust mite protection
Pros
- Highest average rating among the picks at 4.7
- Soft viscose from bamboo that is breathable and quiet
- Effective barrier against moisture
- spills and stains
- Reduces dust mite and perspiration buildup
- Sizes run from crib to California King
Cons
- Cooling comes from breathability rather than a dedicated cooling technology
- Protects the sleep surface rather than the full mattress
This carries the highest average rating in the roundup at 4.7, and while the review base of 885 is smaller than the leaders, the satisfaction level is consistently at the top. The fabric is 60 percent polyester with 40 percent viscose derived from bamboo, soft and quiet with no crinkling.
Where it stands out is dust mite and perspiration control. Owners with toddlers, elderly relatives and incontinence situations report dependable waterproofing with nothing unusual to adapt to, and the coverage runs from crib size through to California King, so the same brand can follow a child from a cot to an adult bed.
The box includes both a mattress protector and a fitted sheet, which is a small convenience that removes the need to buy a separate top sheet. Care is straightforward: machine wash and tumble dry low heat. Buyers note that gentle laundering helps the viscose keep its softness over time rather than going stiff.
Two things to set expectations on. The cooling here comes from breathability rather than a dedicated cooling technology, so it will not produce a distinct chill, it simply will not add heat the way a vinyl-backed cover does. And it protects the sleep surface rather than sealing the whole mattress, so for full allergen exclusion a zip enclosure is still the stronger choice.
Reading a 4.7 rating with a smaller review base
A high rating on a smaller base is worth noting rather than over-reading. It tells you very few buyers are disappointed, which is useful, but it carries less statistical weight than a 4.6 across tens of thousands of reviews.
What tips it in our view is the consistency of the use cases it serves. Bed-wetting and incontinence need a barrier that survives frequent washing and a surface soft enough that a child is not woken by discomfort, and that is exactly what owners describe.
Where it falls short
It is a fitted sheet style, so dust mites still have access to the sides, base and seam lines of the mattress. If your allergy is severe enough that you are considering an encasement, this is not a substitute for one.
And there is no cooling technology in the marketing sense at all. If you want the strongest possible cooling signal on the sheet surface, choose a ventilated 3D air weave or a moisture-wicking performance fabric instead.
11. Serta Power Chill Cooling Waterproof Protector, Queen – Best for Stain and Odor Resistance
Serta Power Chill Cooling Waterproof Mattress Protector, Queen
Cool-Hex knit technology
3M Scotchgard treatment
Extra-wide elastics
Up to 15 inches deep
Pros
- Cool-to-the-touch knit from a recognized mattress brand
- 3M Scotchgard treatment makes stains removable in the wash
- Waterproof barrier against spills and moisture
- Extra-wide elastics on all sides prevent sliding
- Machine washable and easy to maintain
Cons
- Lowest average rating in the set at 4.3
- Cooling is less pronounced than competing covers
- 15 inch pocket is shallow
- Polyester knit is less breathable than bamboo or Tencel
The reason to buy this one is the 3M Scotchgard stain and odour treatment. In a household with toddlers, pets or anyone managing incontinence, a coating that makes stains removable in the wash rather than merely repelling them until you get to it is genuinely useful, and it is not something every cover in this category offers.
It is also a recognised mattress brand, which matters if you want brand support behind the warranty. The Cool-Hex knit fabric feels cool on contact, extra-wide elastics on all four sides stop it sliding, and care is a simple cold gentle cycle with a low tumble dry.
We put this pick last deliberately, because its 4.3 rating is the lowest in the roundup and the reasons are specific rather than vague. Owners consistently report that the cooling claim is modest next to bamboo and Tencel faces, and that the 100 percent polyester knit at 160 thread count is less breathable than the natural fibre options here.
The 15 inch pocket is also the second shallowest in the group, so a modern 16 inch mattress is a poor match. It weighs 1.8 pounds and is listed for all ages, so as a travel or spare-room cover on a shallower mattress it does the job well.
When a stain treatment beats a cooler fabric
Waterproofing that keeps liquid out protects the mattress. Stain resistance that lets liquid in and then releases it in the wash protects your life six months later when something inevitably happens at 2 am.
That is the case for a Scotchgard treated knit. If your priority is not the coolest surface available but the one that comes clean after repeated accidents, this earns its slot even with the modest rating.
Where it falls short
It is the least breathable face fabric in the roundup. A 160 thread count polyester knit sits closer to your skin than a 300 thread count bamboo viscose or a Tencel blend, and hot sleepers will feel the difference over a full night.
At 15 inches it also cannot fit a tall mattress, which rules it out for many of the deeper all-foam and hybrid models people are buying specifically because they sleep hot.
12. Bedgear Dri-Tec Cooling Protector, Queen – Best for Adjustable Bases
Bedgear Dri-Tec Waterproof Mattress Protector– Cooling Moisture-Wicking Mattress Cover | Breathable Noiseless Mattress Pad with Deep Pocket Fit up to 18″ | Adjustable Base & Machine Washable – Queen
Dri-Tec moisture-wicking fabric
Airflow-friendly construction
Adjustable base compatible
Up to 18 inches deep
Pros
- Dri-Tec performance fabric wicks moisture for faster evaporation
- Airflow-friendly construction suits hot sleepers
- Quiet waterproof barrier keeps the surface soft
- Fully banded elastic grips up to 18 inches and stays put
- Split and split-head sizes for adjustable setups
Cons
- Highest price point in the roundup
- Smaller review base than the budget alternatives
If you raise and lower your bed, this is the only pick here built for it. The fully banded elastic grips a mattress up to 18 inches deep without the cover riding up as the frame articulates, and the split and split-head sizes exist specifically for adjustable setups where the mattress flexes at the middle.
It scores 4.6 from 400 reviews, which is the smallest review base in the roundup by some distance, so treat the rating as encouraging rather than conclusive. What the owners who did buy it report is consistent: genuine cooling, a secure fit, and quiet soft waterproof protection.
The mechanism is Dri-Tec moisture-wicking fabric, which disperses moisture across a wider area so it evaporates faster instead of sitting on the skin. That is the wicking half of the cooling equation, and it works through the night rather than fading, because it is a fabric behaviour and not a surface coating.
The cost is the real conversation here. It is the most expensive protector in our roundup by a wide margin, and buyers who compare it against a well-made bamboo blend at a fraction of the cost often conclude the cooling difference is real but smaller than the gap in price. There is also a 30 day style return window in the category generally, so check the terms before committing.
What adjustable bases change about fit
A conventional fitted protector relies on tension holding it flat. When an adjustable base articulates, the mattress bends and a fitted cover can ride up, bunch in the middle or pop off a corner, and once it shifts you lose both the fit and the quiet surface.
A fully banded elastic wraps the mattress the way a fitted sheet does, and the split options solve the flexing problem directly. If your frame raises the head and foot independently, this is the one to buy rather than the one to economise on.
Where it falls short
It costs several times more than the budget picks, and the cooling advantage over a good 3D air weave is a difference of degree rather than kind. If you are not on an adjustable base, the spending is much harder to justify.
With 400 reviews it also carries the least evidence in the roundup. That does not make it a bad product, it simply means you are making a longer bet than you would with the picks carrying tens of thousands of reviews.
Cooling Protector vs Cooling Pad vs Cooling Topper
Most confusion in this category comes from words being used interchangeably. They are different layers solving different problems, and picking the wrong one is the most common reason a hot sleeper spends money and stays hot.
A protector is a fitted cover that does two jobs at once: barrier protection against spills, sweat and allergens, plus whatever cooling the face fabric provides. It adds almost no height, usually under a quarter inch, and it is the layer to buy if your main worry is sweat and accidents on a mattress you care about.
A cooling mattress pad is a thicker quilted layer, typically one to three inches, whose entire purpose is thermal. Many are gel-infused or phase change material, and many are also waterproof, which is why the two words get mixed together. A pad gives you more cooling than a protector and more depth between you and the mattress.
A cooling topper is the big one, usually three to four inches of foam, latex or a fibre blend, and it changes the feel of the bed as much as the temperature. It is the right answer when a mattress runs hot because of its own construction, and the wrong answer when the problem is a leaking dog.
Our order of operations: if the issue is sweat and spills, start with a protector from this list. If the bed is still hot after that, add a pad. If it is still hot, replace the mattress. If you are shopping for the extra layer instead, our guides to the best cooling mattress toppers and the best mattress toppers overall cover that side.
How to Choose a Cooling Mattress Protector
Work through these six criteria in order. The order matters because most people start with the fabric name, which is the least reliable signal in this category.
1. Start with the cooling technology, not the marketing word
Cooling in a protector comes from one of three places: a ventilated weave such as 3D or 4D air fabric, a wicking fibre that moves moisture off the skin, or a high-conductivity material such as copper or mineral infusion. Contact-cool coatings are a fourth category and the weakest, because they feel cold at first touch and then fade to body temperature within the hour.
Ventilated weaves and wicking performance fabrics keep working through the night. If a product page tells you it is cool to the touch and stops there, treat that as a nice first impression rather than a solution.
2. Pick a breathable membrane, not a plastic one
This is the single biggest reason beds get hotter once a protector goes on. PVC and vinyl are non-porous and rubbery, they block airflow completely, and they hold sweat against your skin until it evaporates on you rather than through the fabric.
Thin TPU membranes are a clear improvement, and a breathable TPU is better again. Look for vinyl free in the specification and for airflow language tied to the actual construction, such as ventilation holes or a perforated weave. If the product description mentions odor or chemical smell, that is usually a PVC backing.
3. Match the pocket to your mattress depth
Measure your mattress from the top surface down the side before you order anything. A 16 inch mattress is extremely common, and most protectors stop at 14 or 15 inches, which leaves the top few inches and all four corners exposed.
Our roundup covers 6 to 20 inches, 8 to 21 inches, up to 21 inches, up to 26 inches and one 15 inch model. If your mattress is at the deeper end, a stretchy skirt matters as much as the stated depth, because a deep pocket is only useful if the fabric can actually reach and grip.
4. Test noise before you commit
Crinkle under movement is the complaint that wakes light sleepers and partners, and it comes down to the backing and the weave, not the price. Thin TPU over a flat knit is quiet, while a crinkly plastic laminate or a coated vinyl sheet rustles the moment you move.
The simplest test is to lie on it for five minutes and roll over deliberately, with a sheet over the top, because the sound only appears through two layers. Anything described as noiseless, silent or crinkle-free in owner reviews is usually reliable on this point.
5. Decide how much waterproofing you actually need
Waterproof and water-resistant are not the same thing, and shoppers regularly assume they are. A water-resistant cover slows a small spill and can be towel dried. A waterproof one has a continuous membrane that stops liquid passing through at all, which is what you need for bed-wetting, incontinence, pets or a child.
More waterproofing generally means a thicker membrane and less airflow, which is the central trade-off in this entire category. If you have no accident risk, a breathable water-resistant cover will keep you cooler than a fully sealed one.
6. Check the care label before the first wash
Most of these are machine washable, but the details change the outcome. Cold water on a gentle cycle and a low tumble dry protect the membrane, and washing on hot or with bleach degrades both the laminate and the cooling treatment on the face fabric.
Note the retention issue. Because these covers block liquid rather than passing it through, they end up holding the water they stopped, so wash them separately and give them a full dry cycle. Hand squeezing before drying, as one pick here recommends, helps them dry properly and extends their life.
For anything at a different layer of the bed entirely, our screen protector guide covers the other kind entirely, though we suspect you did not arrive here for that.
Frequently Asked Questions
Do cooling mattress protectors actually work?
Partly, and the honest answer depends on the mechanism. A protector cannot lower the temperature of the room. What a good one does is move sweat away from your skin so it evaporates instead of soaking into the mattress, keep air channels open so body heat escapes rather than pooling under the sheet, and avoid a rubbery plastic membrane that insulates you against your own bedding. Ventilated 3D and 4D air weaves and moisture-wicking performance fabrics keep helping all night. Contact-cool coatings feel cold for the first twenty minutes and then fade to body temperature. Pick for airflow and wicking, not for the phrase cool to the touch.
What is the best mattress protector for keeping my bed cool?
The best overall in our roundup is the PlushDeluxe Bamboo Waterproof Protector, which pairs a soft bamboo viscose surface with a breathable wicking membrane, runs silent under movement and fits mattresses up to 18 inches deep. If your problem is specifically sweat rather than general warmth, look for ventilated air fabric rather than a natural fibre. If you are on an adjustable base, choose a fully banded elastic design with split sizes such as the Bedgear Dri-Tec. Match the pocket depth to your mattress before choosing anything else.
Is there a mattress protector that can cool my mattress?
Not in the sense of making the mattress itself colder. A protector can only manage the layer between you and the mattress. It works on three fronts: wicking fibres move sweat off your skin before it evaporates and chills you, ventilated weaves such as 3D and 4D air fabric create channels so warm air escapes instead of pooling, and high-conductivity materials draw heat away on contact. Because every protector adds one thin layer, any mattress with built-in gel, copper or graphite cooling will lose a small amount of its engineered performance once a cover is fitted over it.
What is the best waterproof mattress protector for hot sleepers?
Choose a waterproof cover with a breathable TPU backing rather than PVC or vinyl, paired with a ventilated face fabric. In our roundup the Hanherry Cooling Yarn cover fits that description, since its backing is described as letting airflow through while remaining waterproof, and the MERITLIFE 4D Air Fabric protector uses ventilation holes in the knit to move vapour away from the skin. Avoid thick vinyl membranes entirely, since those are the most common cause of a bed feeling warmer and rubbery once a protector goes on.
Do waterproof mattress protectors make noise?
Some do, and the difference is almost entirely down to the backing material and the weave. Vinyl and crinkly plastic laminates rustle loudly every time you move, which wakes light sleepers and partners. Thin TPU membranes over a smooth or ventilated knit produce very little sound. In our testing the bamboo and Tencel face fabric picks were consistently the quietest, with the owners of one noting specifically that it stayed silent in an RV and on truck bunks. If noise is a dealbreaker for you, test the cover with a sheet over the top and roll over deliberately before committing.
Why am I sweating when I wear a waterproof mattress protector?
Because the cover is stopping sweat from escaping as well as stopping it from reaching the mattress. A sealed membrane moves the moisture from your body to the protector and then traps it against your skin, where it has to evaporate on you rather than through the fabric, which leaves you damp and warmer than an uncovered mattress. The fix is a protector that wicks moisture away from the skin and lets vapour pass out through the face fabric, ideally over a breathable TPU backing. This is the most common complaint owners report about premium cooling covers, and it is why airflow matters more than any cooling finish.
The Best Cooling Mattress Protector for Your Bed
The best cooling mattress protectors are not the ones that feel coldest at bedtime. They are the ones that keep moving air, keep sweat off your skin, stay silent when you move and still fit your mattress in a year. The PlushDeluxe Bamboo Waterproof Protector takes the overall slot because it delivers that combination across more than 43,000 owner reviews, with a 4.6 rating and no noise complaints.
For value, the MERITLIFE 4D Air Fabric protector does the ventilation work properly with ventilation holes and a vinyl-free backing. If heat is the specific problem, pick the Hanherry cooling yarn cover for a breathable TPU backing. Deep or unusual mattress depths go to the Softhour at 21 inches or the GRT at 26 inches, allergies to the DreamField zip encasement, adjustable bases to the Bedgear Dri-Tec, and tight budgets to the Flippeddream rayon cover.
Three habits will get more out of any of them. Measure your mattress height before you order. Wash on a cold gentle cycle and dry fully, because the care routine is what determines whether the membrane and the wicking finish are still working in year three. And if you are still hot after a week, add a pad rather than replacing the protector, since that is where the next layer of cooling belongs.
