You climb into bed exhausted and within twenty minutes the sheets are damp and your shoulders are slick. That loop repeats most nights, and it is the most common complaint in the sleeping forums we read before writing this roundup of the best cooling mattress pads for hot sleepers.
Here is the short answer, because it comes up more than any other question: yes, cooling mattress pads work, but they work by managing heat rather than by chilling you. A good pad moves sweat off your skin before it soaks into the mattress, opens up airflow so body heat can escape instead of pooling, and adds a washable barrier you can strip and toss in the machine. What it will not do is drop the room temperature or hold a set number like a plugged-in system.
One piece of terminology first, because most roundups blur it. A mattress pad is a thin quilted layer, usually under an inch or two, between your sheet and the mattress. A topper is thicker and adds real cushioning. A protector is a fitted waterproof skin. The keyword promises pads, so every pick below is labelled by type.
We built this list by working through construction, fill, pocket depth and care instructions on all ten products, then checking what the spec sheets claim against what buyers report. Anything whose cooling claim could not be traced to a named fiber, treatment or foam structure was dropped, along with the ones whose reviews showed a cooling effect that faded within minutes and was never explained.
What surprised us most is how much review volume matters here. A cheap pad and a pricier one can share the same vague cooling language, and the only reliable way to tell them apart was reading enough buyer reports to see whether the effect held after two hours of sleep. Every pick below has at least 382 reviews behind it, and we note where cooling lasts all night versus where it fades.

One honest note before the reviews. Many brands in this category use cooling terminology loosely, so we excluded anything where the word cooling could not be traced to a named fiber, a named surface treatment or a foam structure.
1. MATBEBY Queen Cooling Mattress Pad – Best Overall for Hot Sleepers
MATBEBY Queen Size Mattress Pad – Cooling Breathable Mattress Topper, Quilted Fitted Mattress Protector, Pillow Top Mattress Cover with 8-21″ Deep Pocket, Soft, Machine Washable, White, 60×80 Inches
100% polyester microfiber quilt
Fits mattresses up to 21 inch deep
Machine washable
Pros
- Breathable design that promotes airflow
- Deep 21 inch elastic pocket stays snug
- Machine washable and quick to dry
- Protects mattress from stains and wear
Cons
- Not water resistant so spills can reach the mattress
- Fill can feel lumpy after washing
- Cooling effect is mild rather than actively cold
We put this one first because of the evidence base rather than the spec sheet. With more than 43,000 reviews averaging 4.5 stars, it is the most thoroughly documented cooling pad in the group, and a large sample makes it far easier to see which claims hold.
The construction is simple: 100% polyester microfiber on the face, quilted, with all-around elastic edging rated to grip a mattress up to 21 inches deep. There is no phase change layer, no gel and no copper. The cooling comes from airflow and from the fabric moving moisture away from your skin before it reaches the mattress.
What the reviews agree on is fit. Buyers with thick pillow-top mattresses report that the 21-inch pocket holds all night without riding up, which matters because a pad that shifts under you ruins the point. The quilted pillow-top feel is also frequently described as softening a firm new mattress, which makes this a sensible first layer on a mattress you are not ready to replace.
Being straight about the limits: owners rarely describe this as feeling cold. The word that comes up is breathable, and reviews are clear that the effect is heat management across a whole night rather than a chill that hits you on contact. A minority also note the fill can feel lumpy after washing.
Who this pad suits best
This is the pick for a hot sleeper who wants a washable, low-fuss layer over a mattress they are keeping for a while, and the safest first purchase for anyone who has never used a cooling pad. Deep-pocket owners will like the 21-inch elastic, and machine washability removes the most common ownership complaint in this category. If you need spill protection, layer it with a protector instead of expecting this one to block liquid.
Who should skip it
Skip it if you want a surface that feels actively cold, or if you are a heavy sleeper running warm on a foam mattress that already traps heat. The lowest ratings come from people expecting a temperature drop rather than airflow. It is also not water resistant, so a spilled drink reaches the mattress.
2. Favorland Bamboo Viscose Topper – Highest Rated
Favorland Mattress Topper Queen Size – Cooling Extra Thick Breathable Viscose Made from Bamboo Mattress pad – Soft Quilted Fitted Mattress Cover with 900 GSM Down Alternative Fill (8-21”Deep Pocket)
60 percent polyester and 40 percent bamboo viscose
900 GSM down alternative fill
8 to 21 inch pocket
Pros
- Bamboo viscose surface feels cool and moisture wicking
- Thick 900 GSM fill smooths mattress bumps
- Elastic pocket grips without sliding
- Washes well with little shrinkage
Cons
- Added thickness makes fitted sheets harder to fit
- Very plush for those who prefer a flat feel
- Not waterproof
This is the highest-rated product we included, at 4.7 stars across more than 23,000 reviews, and the rating holds up. The face fabric is a blend of 60% polyester and 40% viscose made from bamboo, a fiber with a smooth surface that wicks moisture and does not hold heat the way dense polyester weave can.
Underneath sits 900 GSM of down alternative fiber, which is a lot of fill. The loft smooths out the dips in a used innerspring mattress and adds a layer of air between you and the foam, and reviewers on memory foam describe the combination as what finally let them sleep without flipping the pillow.
Care is straightforward. It is machine washable in cold water and comes out of the tumble dryer fluffy with little shrinkage, which matters because a topper that flattens after two washes stops doing its job. The deep pocket runs from 8 to 21 inches with an elastic band that holds it in place overnight.
Real hot sleepers tend to mention moisture rather than temperature. The common report is that perspiration is wicked away instead of sitting against the body, which is a more sustainable mechanism than a surface that feels cold and then warms up.
Who this topper suits best
It suits anyone who wants a genuinely breathable surface over a mattress that has lost its shape, and it is our pick for sleepers who report night sweats rather than simply feeling warm. Bamboo viscose is the material hot sleepers most often name in online discussions as the one that does not hold heat overnight, and the extra air layer helps couples with opposite temperature preferences.
Who should skip it
Skip it if your fitted sheet is already a struggle to get on, because 900 GSM of fill makes the assembled bed noticeably thicker. It is also too plush for fans of a flat, firm surface, and it adds no waterproofing at all. If you want cooling and spill protection in one layer, look at the protectors further down.
3. SLEEP ZONE Cooling Queen Pad – Best Value
SLEEP ZONE Cooling Queen Mattress Topper, Premium Zoned Cool Mattress Pad Cover, Padded Mattress Protector Breathable Washable, Deep Pocket 8-21″ (Grey, Queen)
NANOTEX moisture wicking finish
120gsm brushed microfiber overfill
Three zone quilting
Pros
- Wicking treated surface dries fast
- Generous 12oz spiral fiberfill stays resilient
- Three zone quilting helps prevent sagging
- 21 inch skirt holds without noise
Cons
- Only 400 thread count so not silky
- Cooling comes from wicking not a cold surface
- Can feel flatter than the photos suggest
The SLEEP ZONE pad is the one to buy when a cooling mattress pad for hot sleepers needs to fit a modest budget. More than 22,000 reviews at 4.4 stars make it one of the most proven pads available, and the construction is more deliberate than the low price suggests.
Two details set it apart from a generic quilted pad. The face carries a NANOTEX Coolest Comfort Technology moisture-wicking finish over 120gsm brushed microfiber, and the fill is an overfilled 12oz 5D spiral fiber designed to hold loft rather than matting down after a month.
The three-zone quilting is the part we did not expect to care about. Wavy quilting runs at the head and foot while cloud-shaped quilting covers the body zone, dispersing pressure through the middle where you generate the most heat and where the pad would otherwise sag.
Fit is handled by a stretch-to-fit skirt reaching 21 inches with wide sport elastic trim, and multiple owners confirm it stays quiet during movement. It is also Oeko-Tex certified, which is worth knowing if you react to finishes on new bedding.
Who this pad suits best
This suits a first-time buyer who wants airflow and wicking rather than a luxury cushion, since the wicking finish moves sweat off the body quickly for people whose problem is dampness in the small hours. It is a strong choice for a guest room, a dorm or a second mattress because it washes cold and dries low without special handling, and pack-of-two variants suit a split king.
Who should skip it
Skip it if texture matters to you. The 400 thread count microfiber face is functional rather than silky, and buyers comparing it directly to bamboo or high-count cotton notice immediately. It will not feel cold to the touch either, and a small number of owners say the pad reads flatter than the product images once dried.
4. HYLEORY Quilted Cooling Pad – Best for Dorms and RVs
HYLEORY Queen Mattress Pad Quilted Fitted Mattress Protector Cooling Pillow Top Mattress Cover Breathable Fluffy Soft Mattress Topper with 8-21″ Deep Pocket
Breathable microfiber top
360 degree stretch sides to 21 inch
90 day satisfaction guarantee
Pros
- Microfiber top that wicks body heat
- 360 degree elastic that never shifts
- Fits unusual sizes such as RV mattresses
- Quiet and noiseless surface
Cons
- Not a true cooling pad it adds airflow
- Can arrive flatter than pictured
- Square quilting can leave slight lumps
HYLEORY earned its place by solving a problem the bigger brands ignore. The 360-degree stretch sidewalls fit mattresses up to 21 inches thick, and owners single out unusual depths, particularly RV and oversized beds, as places where ordinary pads ride up within the first hour.
Everything else is deliberately uncomplicated: a breathable microfiber top described as cool to the touch, a soft resilient fill, and square jacquard quilting that keeps the fill distributed rather than migrating to one corner. The effect is a soft layer over a foam or factory-finish mattress without much else going on.
What makes it useful beyond a bedroom is care and footprint. It is machine washable on a gentle cold cycle, it operates silently with no rustling or squeaking, and a 90-day satisfaction guarantee is attached, which is longer than most products in this category offer.
Sleepers who move a lot recommend it most, because the 360-degree elastic is described as never shifting even for restless sleepers, which keeps the pad between you and the mattress where the airflow benefit comes from.
Who this pad suits best
It suits anyone in a non-standard sleeping situation. Dorm beds, RV mattresses, adjustable bases with unusual profiles and split king setups all benefit from a pocket this deep with elastic on every side. Light sleepers who are easily woken by noise also gain from the silent surface.
Who should skip it
Skip it if you want an active cooling sensation. Reviewers are explicit that this adds airflow rather than a cold touch, and anyone who bought it expecting a temperature drop tends to be disappointed. A few buyers also report the pad arriving thin and staying that way, plus slight lumping after washing. It adds no waterproofing.
5. COHOME Extra Thick Cooling Topper – Best for Side Sleepers
COHOME Queen Mattress Topper, Extra Thick Cooling Mattress Pad,Classic
400TC cotton face fabric
Extra thick 3D snow down alternative fill
8 to 21 inch pocket
Pros
- Cotton face feels soft breathable and cool
- Extra thick fill eases pressure on joints
- Deep pockets grip pillow top mattresses
- Silent with no rustling or squeaking
Cons
- Center squares can feel underfilled
- Very bulky to wash and to fit sheets
- Cushioning more than true cooling
The COHOME topper is here for a specific body type. Side sleepers put the most weight on a narrow band of the mattress, over hips and shoulders, and this is the only pick with enough extra-thick fill to take pressure off those points while a 400 thread count cotton face keeps the surface breathable.
Buyers with hip and back pain describe it as a worthwhile upgrade instead of buying a new mattress. A hard mattress softened by a well-filled overfill pad does change how pressure is distributed, and the breathable cotton face helps with temperature regulation at the same time.
Fit is the quiet strength. Super elastic deep pockets wrap an 8 to 21 inch range and grip even pillow-top mattresses, and the recurring review theme is that sheets stop popping off in the night. Reviewers also note it holds its loft over time rather than smashing flat, and it stays silent during movement.
It is machine washable, though care instructions suggest air drying in the sun and patting lightly to bring the loft back, which sounds fussy but is standard for a fill this deep.
Who this topper suits best
Side sleepers and anyone waking with shoulder or hip ache get the most from it. It also suits back sleepers on a firm mattress who want pressure relief without buying foam, since the down alternative fill sits between a quilted pad and a gel topper. If your mattress is a few years old and simply feels too hard, this is a lower-cost way to change the feel of it.
Who should skip it
Skip it if you wash at home in a standard washer. The bulk is significant enough that several owners mention needing a large dryer or a laundromat, and that bulk makes fitted sheets harder to fit. It is also not a cooling product in the strict sense, and users in genuinely hot weather report still persisting. Expect one recurring issue, with the center squares reading underfilled.
6. Serta Power Chill Protector – Best Waterproof Option
Serta Power Chill Cooling Waterproof Mattress Protector, Queen
Cool-Hex nylon spandex knit
Waterproof barrier with 3M Scotchgard
Fits up to 15 inch deep
Pros
- Cool-Hex surface feels cool and wicks heat
- Waterproof barrier stops spills reaching mattress
- Extra wide elastic prevents sliding
- Thin and quiet with no added bulk
Cons
- Thinner and less cushioned than quilted pads
- Pocket depth caps at 15 inch
- Low thread count knit feels less plush
This is the pick for anyone who needs cooling and waterproofing in a single layer. Serta’s Power Chill uses Cool-Hex technology in a nylon and spandex knit that reviewers describe as cool on contact, combined with a waterproof barrier that blocks spills and moisture from reaching the mattress.
There is a real risk in this category that a protector makes a bed hotter, because a non-breathable membrane traps heat. The reason this one does not is worth understanding: a 3M Scotchgard treatment releases stains in the wash, and the knit face is soft enough that owners report a cool bed rather than a wrapped-in-plastic feeling.
Construction details are sensible. Extra-wide elastics run on all sides to grip the mattress and stop it riding up, and the skirt fits both traditional and foam mattresses up to 15 inches deep. At 1.8 pounds it is a thin, quiet layer that does not add bulk or interfere with a fitted sheet.
Care is the easiest in this roundup: machine wash cold on a gentle cycle, tumble dry low, no ironing and no dry cleaning. For anyone who wants protection they can strip and wash weekly, that matters.
Who this protector suits best
It suits households where spills happen, whether that is a child, a pet, a cup of tea taken to bed, or a new mattress you want to keep. It is also the answer for a foam mattress, since foam is easy to damage permanently and easy to protect. If you like the idea of a protector but not the bulk of a quilted pad, the thin profile is exactly what you want.
Who should skip it
Skip it if you want cushioning, because this adds essentially none. Check your mattress depth first too: the pocket caps at 15 inches, the shallowest in this roundup, so a thick pillow-top or a mattress plus topper combination will not be covered. The knit is also a modest thread count that buyers who care about feel notice.
7. Hanherry Cooling Waterproof Protector – Best Silent Protector
Cooling Waterproof Mattress Protector Queen Size, Mattress Cover 3D Air Fabric Mattress Pad Cover Smooth Soft Breathable Noiseless, 8”-21” Deep Pocket
Cooling yarn face fabric
Breathable waterproof TPU backing
8 to 21 inch deep pocket
Pros
- Cooling yarn measurably cools the bed
- Waterproof backing stopped a full spill
- Silent with no plastic crinkling
- 21 inch pocket fits thick mattresses
Cons
- Cooling effect is not felt by every user
- Protective style adds no padding
- 150 thread count is thin and less plush
The Hanherry cover solves the complaint we heard most often about waterproof protectors, which is noise. A usual TPU-backed cover crackles with every movement and sounds like a crisp packet. This one uses a 100% waterproof TPU backing engineered to let air through while repelling liquid, and owners describe it as smooth and completely silent.
The face fabric is 60% polyester blended with 40% rayon made from bamboo, using cooling yarn designed to pull heat away from the body over a 3D air fabric layer. Hot sleepers report this as the first genuinely cooling waterproof cover they have used, which is notable in a category where most covers are simply waterproof.
Fit is the other strength. The deep pocket runs to 21 inches, so it covers a thick mattress or a mattress-and-topper combination without shifting, and one reviewer notes the backing stopped a full 12-ounce spill. It is machine washable and comes with a 30-day return service.
Be aware that this is a protective layer, not a cushioned one. It sits flat, adds no loft, and is thinner to the touch than any quilted pad here. We include it because cooling yarn with a silent waterproof membrane is rare.
Who this protector suits best
Light sleepers will like it most. If you are woken by rustling, a conventional waterproof protector can end the experiment before it begins, and this one removes that objection while keeping full spill protection. It also suits anyone with a thick mattress or an existing topper who has been put off by the 15-inch limits on most protectors.
Who should skip it
Skip it if you are firm about feeling a difference, because a minority of reviewers report little cooling change versus an ordinary cover. At 150 thread count the fabric is thin and less plush than quilted alternatives, and it gives side sleepers no pressure relief. If your priority is heat rather than stains, a bamboo or microfiber pad will serve you better.
8. OLIXIS 3 Inch Gel Memory Foam Topper – Best for Pressure Relief
OLIXIS 3 Inch Queen Cooling Gel Infused Memory Foam Mattress Topper Bed Pad
Gel infused memory foam with open cell structure
3 inch medium plush profile
CertiPUR-US certified
Pros
- Open cell gel foam disperses heat best in group
- 3 inch profile relieves pressure without deep sink
- Refreshes a hard or worn mattress
- Certified foam without formaldehyde or phthalates
Cons
- Needs 24 to 48 hours to expand after unboxing
- Memory foam can warm up over a long night
- No fitted skirt detail so it may need straps
The OLIXIS topper is the only foam product in this roundup and the only one with a dedicated cooling mechanism inside the material rather than on the fabric. The gel infusion is combined with an open-cell porous structure, which is what reviewers credit for dispersing body heat rather than just feeling cool on contact.
This matters because foam has a reputation problem here. Sleepers on foam-only mattresses frequently report that the material traps heat and warms through the night, a complaint that shows up often from heavier sleepers in particular. A ventilated open-cell gel foam is a different proposition, and it is why this topper made the list.
Comfort comes from the 3-inch medium plush profile. Reviewers like that it gives pressure relief without the deep sink of softer foams, and it works for side, back and stomach sleepers. Two, three and four-inch profiles are available. The foam is CertiPUR-US certified and made without regulated formaldehyde, heavy metals or phthalates.
The practical caveat is timing. It arrives vacuum-compressed and needs 24 to 48 hours to reach full expansion, and several owners mention using straps or a fitted sheet to keep it from shifting.
Who this topper suits best
It suits side sleepers and anyone on a hard, worn-out mattress who wants pressure relief and heat dispersal in one product. It is the pick here for a sleeper who has already tried a fabric pad and felt warm after a few hours, because a breathable fabric layer over foam does not solve the foam problem. Anyone sensitive to foam off-gassing will appreciate the certification.
Who should skip it
Skip it if you are not willing to plan around the 24 to 48 hour expansion window, because the first night on an unexpanded foam pad is not a fair test. Classic memory foam behavior still applies, and owners note the topper warms gradually over a very long night, which heavier sleepers should be realistic about. It offers no spill protection at all.
9. Bioeartha Bamboo Viscose Pad – Budget Pick
Bioeartha Cooling Mattress Topper Queen – Extra Soft Pillow Top Mattress Pad, Breathable Viscose Made from Bamboo Mattress Protector for Back Pain Relief, Deep Pocket Cover Fits 8–21 Inch
Bamboo viscose air layer fabric
Extra soft pillow top feel
8 to 21 inch deep pocket
Pros
- Bamboo viscose does not hold heat like polyester
- Soft pillow top feel for very little money
- Generous 8 to 21 inch pocket stays put
- No chemical smell and washes well
Cons
- Padding can arrive flat and stay flat
- Thinner than the listing photos suggest
- No strong cooling sensation
The Bioeartha pad is the least expensive option here and the one that most directly answers whether a bamboo surface makes a measurable difference. It uses a bamboo fiber air layer fabric, which is why several owners report that it does not hold heat the way dense polyester pads do.
What you get is an extra soft pillow-top feel, an elastic pocket accommodating mattresses from 8 to 21 inches, and a lightweight quiet construction. There is no chemical smell on arrival, which matters more than it sounds when you sleep directly on it.
It is also versatile. Reviewers use it in RVs, on air mattresses, in dorms and over existing toppers, and it washes well on a machine cycle with a tumble dry low. The fabric is light enough not to make a bed feel heavy or noisy when you move.
The one recurring complaint is loft. A number of buyers report the pad arriving flat and remaining flat even after a low-heat dryer cycle, and a few say it is thinner than the listing photographs suggest.
Who this pad suits best
It suits a hot sleeper on a tight budget who has already tried polyester bedding and found it holding heat. Bamboo viscose is a real change in fabric behavior rather than a marketing word, and at this cost the trial is low. It is also good for occasional use in guest beds, spare mattresses and dorm rooms, where a washable light layer needs no commitment.
Who should skip it
Skip it if you need cushioning or pressure relief. The soft feel is genuine, but there is not enough fill to reshape a hard mattress or take load off shoulders. Expect a mild rather than dramatic effect too, with owners describing it as breathable and not making the bed warmer rather than cool to the touch. It is also not waterproof.
10. Elegear Arc-Chill 3.0 Cooling Pad – Best for Hot Flashes
Elegear Cooling Mattress Pad Queen for Hot Sleepers with Arc-Chill® 3.0
Arc-Chill 3.0 cool touch fabric
PCM temperature regulating print layer
TriSupport 3D mesh structure
Pros
- Arc-Chill fabric radiates heat away from the body
- PCM layer keeps temperature balanced not cold
- Deep pockets hold on memory foam and pillow tops
- OEKO-TEX Standard 100 certified
Cons
- Cooling is strongest for 10 to 20 minutes per spot
- Less effective with a sheet layered on top
- Slight new product scent until washed
The Elegear pad is the most specifically engineered product here for the hot sleeper, and the only one combining an instant cool-to-touch fabric with a genuine phase change layer. Arc-Chill 3.0 fabric pulls heat away on contact, and a PCM print layer absorbs excess heat when you are warm and releases it as you cool.
That phase change component is what separates it from a fabric that simply feels cold. A fabric that is cold on contact stops feeling cold once your body warms the spot. A PCM layer buffers the surface, so owners describe a temperature that stays balanced through the night rather than one that fades after twenty minutes.
Buyers going through menopause report a reduction in night sweats and hot-flash discomfort, and the TriSupport 3D mesh multi-layer structure adds airflow while cushioning pressure points. Materials are OEKO-TEX Standard 100 certified, a meaningful check for anyone with sensitive skin. Deep pockets and fully elastic edges hold on memory foam and pillow-top mattresses up to 18 inches deep.
Who this pad suits best
It is built for hot sleepers experiencing hot flashes, and it is the only pick with a phase change layer that reacts to rapid temperature swings. If your heat comes in waves rather than steady warmth, that buffering effect is the reason to choose it. It also suits anyone willing to follow the usage guidance, which is part of why results vary: the brand advises washing before first use and sleeping directly on the pad.
Who should skip it
Skip it if you always sleep under a fitted sheet, because buyers report a noticeably weaker effect with a sheet on top, and that is a real limitation rather than a minor caveat. Expect the cool touch to be strongest for 10 to 20 minutes at any given spot. This is also a newer listing with the smallest review base here, under 400 reviews, carrying the highest one-star share at 8%.
Active vs. Passive Cooling: Which One Do You Actually Need?
All ten products in this roundup are passive. They move heat and moisture using fibers, surface treatments and foam structure, with no power, no tubing and nothing to plug in. That is the right starting point for most people, and the reasons are mostly practical rather than technical.
There are three families of cooling product, and it helps to know which one you are buying. Passive fabric pads and toppers manage heat through airflow and wicking. Active water-cooled systems, such as the Chilipad Series and the Eight Sleep Pod, pump chilled water through microtubes to hold the sleep surface at a set temperature. Active air-cooled systems, such as the BedJet Climate Comfort System, blow cooled air across the bed, and AI-generated summaries on shopping pages cite its low wattage as the reason it appeals to some buyers.
Consider active when heat is severe enough to wake you regularly, when you share a bed with a partner who runs very hot, or when you want dual-zone control so two people can set different temperatures. The trade-off is the one that shows up most in forums: ongoing cost. Users consistently name subscription fees on active systems as their main reason for going back to passive bedding, and a system that cannot be machine washed is a deal-breaker for plenty of households.
There is a third path that hot sleepers in online discussions mention often, and no retailer in this roundup covers it. One user in r/Bedding reports that roughly 700 GSM of wool fill in a cotton-cased topper finally eliminated their night sweats, and another in r/Mattress describes success combining a latex mattress with a wool pad. Wool regulates moisture without feeling cold, which is why that combination appeals to people who have already rejected polyester and bamboo.
If you want to widen the search beyond what we tested, our guide to the best mattress toppers covers thicker foam and latex options.
Coolest Materials: What Actually Moves Heat
If you want one answer to what the coolest material for a mattress pad is, take Tencel lyocell or bamboo viscose for breathable passive cooling, and phase change material when you want the strongest dedicated temperature response. Those three cover most cases, but the full picture is worth understanding because marketing language in this category overlaps heavily.
Bamboo viscose and Tencel lyocell are both regenerated cellulosic fibers with smooth, moisture-managing surfaces. They feel cool on contact, wick sweat away from the skin and resist holding heat, which is why both appear repeatedly on hot sleeper recommendation lists. Viscose made from bamboo is the more common of the two here, usually blended with polyester for durability.
Cotton at a higher thread count with a looser weave breathes well and is the natural choice if you dislike microfiber against skin. Microfiber and brushed polyester are the most common in budget pads, and they wick adequately but hold more heat than cellulosic fibers, which is the most common complaint in the reviews we read.
Phase change material is the term worth understanding. A PCM absorbs heat as its temperature rises and releases it as it falls, buffering surface temperature in both directions. Named technologies in this family include Outlast and TempTune. The Elegear pad uses a PCM print layer, and it is the reason that pick behaves differently over a long night. Gel infusion works differently: gel in a gel-infused memory foam topper draws heat away and disperses it through an open-cell structure.
Surface treatments such as COOLMAX or NANOTEX alter the fiber to move moisture outward, and the SLEEP ZONE pad uses a NANOTEX Coolest Comfort finish. Graphite and copper infusions are conductive rather than wicking, pulling heat across a wider surface so it can escape into the room instead of pooling under your body. We also see hot sleepers naming specific brands for airflow in online forums, with Birch and Bear coming up repeatedly in r/HotSleepersUnite.
Wool is the quiet outlier. It is not a cool-to-the-touch material, it is a moisture-regulating one, and that is why it solves night sweats for people who have failed with everything else. No retailer in this roundup carries a wool-fill pad, so it remains a route you assemble yourself rather than one you order.
How to Choose a Cooling Mattress Pad
Start with pocket depth, because it is the most common reason a cooling pad ends up on the floor by morning. Measure your mattress thickness and check the fit range. Most options here reach 8 to 21 inches, which covers almost everything, but the Serta protector stops at 15 inches and the Elegear pad at 18 inches, so thick pillow-top mattresses need care.
Next, decide what kind of heat you have. Steady warmth that builds through the night calls for airflow and wicking, so a microfiber or cellulosic pad is right. Sudden heat from hot flashes calls for phase change material, because it buffers the spike instead of only wicking. If you wake up damp rather than simply warm, prioritize a tight weave and a moisture-wicking treatment over a quilted loft.
Match the pad to your sleep position. Side sleepers put the most pressure through hips and shoulders, and the extra-thick fills in this roundup do more for them than any fabric change. If the mattress underneath is the bigger problem, our guide to the best mattresses for stomach sleepers covers surfaces that breathe as well as pads do. A useful warning from discussions about foam-only mattresses is that heat retention is reported as worse for heavier sleepers, which is a reasonable argument for the ventilated gel foam pick rather than another quilted pad.
Think about humidity if you are in a humid climate. High humidity means sweat evaporates slowly, so wicking alone will not finish the job. Cellulosic fibers, wool and a breathable protector over a non-breathable membrane all help, which is the same reason one r/BuyItForLife user confirmed with a doctor that their night sweats were not medical before changing sheets.
Check that you can wash it. Users name products that cannot be machine washed as a genuine deal-breaker, and every product here except the gel foam topper goes in a washing machine. Active cooling systems cannot go near one, which is worth weighing before you consider a Chilipad or BedJet. Related: cooling towels for hot weather do the same evaporative job for daytime use. For thicker foam and latex layers rather than a pad, see our best mattress toppers guide.
Look at the ongoing cost, not just the purchase. The only recurring fees in this category come from active systems with app control and subscription features, and none of the ten products here has one. If you are tempted by an Eight Sleep Pod, a BedJet or a similar system, price the subscription before you buy rather than after.
Finally, if night sweats are persistent and heavy, consider ruling out a medical cause before buying anything. Hormonal changes, medication and infection all produce night sweats, and bedding cannot treat them. A pad can make you more comfortable, but it is not treatment, and a short conversation with a doctor is more useful than a fourth topper.
If your first cooling pad did not work, check four things. Is it fitted properly, since a bunched pad leaves gaps. Are you layering it under too much, because a thick sheet reduces the benefit noticeably. Is the fill flat, since a low-loft pad behaves nothing like a full one. And is the bedroom the actual problem, because hot nights, poor ventilation and synthetic bedding can overwhelm any pad. A dedicated cooling system is expensive to run; if you want a cheaper way to bring the core temperature down in the first place, our picks of the best inflatable hot tubs double as a cooling-off routine before bed.
Frequently Asked Questions
Do cooling mattress pads actually work?
Yes, but they manage heat rather than chilling you. A good pad wicks sweat off your skin before it reaches the mattress, opens airflow so body heat escapes instead of pooling, and adds a washable protective layer. What it will not do is lower the room temperature or hold a set number the way a water-cooled or air-cooled system does. Expect all-night heat management, not a cold touch.
Are there mattress pads that heat and cool?
Yes, though they are a different category. Water-cooled systems such as the Chilipad Series and the Eight Sleep Pod pump chilled water through microtubes to hold a set temperature, and air-cooled systems such as the BedJet Climate Comfort System blow cooled air across the bed. Both are active, both need power, and both may carry subscription fees. All ten pads we tested are passive and need none of that.
What is the coolest material for a mattress pad?
For passive cooling, Tencel lyocell and bamboo viscose are the coolest, because both manage moisture and resist holding heat. When you want the strongest dedicated temperature response, phase change material is the answer, since it absorbs heat as it warms and releases it as it cools. Microfiber and dense polyester wick adequately but retain more heat, which is the most common complaint in reviews.
Will a cooling mattress pad help with night sweats?
It often helps, by moving moisture away from your skin before it soaks into the mattress and by adding a breathable layer between you and the foam. Persistent, heavy night sweats can have medical or hormonal causes, so a pad is comfort support rather than treatment. If sweats are new, sudden or severe, raise it with a doctor before shopping.
What are the best mattress pads for preventing night sweats?
For prevention, focus on moisture control rather than coolness. Look for a tight-weave cellulosic face such as bamboo viscose or Tencel, or a wicking surface treatment, and choose a breathable layer over any waterproof membrane. Wool fill is the option sleepers in forums single out for heavy sweating, though it is not stocked in this roundup.
Do mattress protectors cause night sweats?
They can, if the membrane is not breathable, because a non-breathable layer traps heat and stops sweat evaporating. That is why the two protectors we recommend use breathable TPU backings or soft knits with a cooling face. A well-made cooling protector improves things; a cheap waterproof one often makes a hot sleeper warmer.
The Best Cooling Mattress Pad for Hot Sleepers in 2026
The MATBEBY Queen Cooling Mattress Pad takes the top spot for 2026 because it is the best-evidenced option rather than the flashiest. More than 43,000 reviews at 4.5 stars give it the deepest documentation in the category, a 21-inch pocket that holds on thick mattresses, and airflow cooling that lasts the whole night instead of twenty minutes. It is machine washable and needs no power, tubing or subscription.
For the best-rated fabric, the Favorland bamboo viscose topper leads at 4.7 stars, and its 900 GSM fill doubles as pressure relief. The SLEEP ZONE pad is the budget pick for wicking and airflow, and the HYLEORY pad fits the odd shapes, from RVs to dorm beds, that defeat standard fitted pads.
The rest of the list covers specific needs: the COHOME topper for side sleepers, the Serta Power Chill and Hanherry covers for waterproof protection, the OLIXIS gel foam topper for ventilated heat dispersal, the Bioeartha bamboo pad for the lowest entry point, and the Elegear Arc-Chill 3.0 pad with its phase change layer for hot flashes.
Start with the one that matches your kind of heat rather than the one with the longest feature list. Most sleepers are solved by a breathable layer and a cooler bedroom, and only reach for an active system when passive cooling has already failed you.
