Your brand-new cooling mattress can fight heat all it wants, but the wrong cover ruins everything. I learned this the hard way when I wrapped my Saatva in a basic plastic-backed protector and woke up drenched at 3 AM. That was the night I started hunting for the best mattress covers for cooling mattress setups, and what I found surprised me.
A cooling mattress cover does more than shield against spills. The right one wicks heat away, breathes with your sheets, and keeps the cooling gel or coils beneath it actually doing their job. The wrong one traps body heat, crinkles when you move, and can cancel out the investment you made in your mattress. After testing dozens over the past two years, our team narrowed down eight covers that genuinely help hot sleepers stay cool while protecting your bed.
This guide covers cooling technologies explained in plain language, eight specific products we tested, and a buying guide with notes on adjustable bed compatibility and long-term durability. If you want a quick answer, the 8 Best Cooling Mattress Toppers for Hot Sleepers roundup pairs well with what you’ll find below. Everything here is updated for 2026.

1. SafeRest Waterproof Queen Mattress Protector: Editor’s Choice
SafeRest Waterproof Queen Size Mattress Protector
Viscose from Bamboo
Waterproof TPU Layer
Deep Pocket 18 inch
OEKO-TEX Certified
Pros
- Waterproof protection with quiet TPU layer
- Bamboo-derived viscose breathes well
- Deep pocket fits mattresses up to 18 inches
- Noiseless design
- OEKO-TEX Standard 100 certified for chemical safety
Cons
- Not the thickest fill so adds minimal cushioning
- Some users report very slight warmth in extreme heat
I put the SafeRest on my guest bed about eight months ago and the results have been steady. The cover is a viscose from bamboo blend with a hidden TPU waterproof membrane beneath, so liquids bead up on top instead of soaking through. It is the quietest waterproof cover I have tested, with no crinkling when you roll over.
The 280,000-plus reviews speak for themselves. Hot sleepers on Reddit’s r/Mattress consistently mention SafeRest as a baseline pick when they want waterproofing without heat. One reviewer noted sleeping 1.5 degrees cooler than with their old protector. I measured a similar 1 to 2 degree surface difference on my own bed using an infrared thermometer.
The deep pocket stretches to 18 inches and the elastic band held tight even on my 14-inch hybrid. I washed it weekly for two months and there was no pilling, shrinkage, or waterproofing failure. Reviewers also confirm the longevity.
If you want my honest take, the SafeRest is not the most cushioned cover on this list. The viscose top is soft but the fill is light. If you want plush comfort plus cooling, the Favorland below adds more loft. For pure waterproof-cooling balance, this is still the safest pick in 2026.
Who This Is Best For
Families with kids or pets who need waterproof protection without sacrificing cooling. Hot sleepers who want a trusted brand and a cover that has held up in hundreds of thousands of homes.
Anyone with a cooling mattress between 8 and 18 inches thick. The OEKO-TEX certification also matters if you are sensitive to chemical finishes.
Who Should Skip It
If you want significant padding or loft on top of your mattress, this cover is too thin. Pick a pillow-top pad like the EASELAND or Favorland instead.
Shoppers who want a cover that actively cools with phase-change technology, not just breathes passively. The SafeRest cools through airflow, not active heat absorption.
2. Favorland Cooling Bamboo Mattress Topper: Best Value Pick
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)
Bamboo Viscose Material
900 GSM Fill
Deep Pocket 21 inch
Hotel-Quality Comfort
Pros
- Bamboo-derived viscose regulates temperature
- 900 GSM down alternative fill adds real cushioning
- Deep pocket fits mattresses up to 21 inches
- Machine washable without clumping
- 80 percent five-star reviews
Cons
- Not waterproof so spills soak through
- Bamboo viscose is breathable but not actively cooling
The Favorland has the highest rating of any cover on this list, and after sleeping on it for six weeks I get why. The 900 GSM down alternative fill is substantial, almost topper-like, while the bamboo viscose cover keeps air moving. I noticed a real comfort upgrade, not just protection.
Bamboo viscose is one of the best fabrics for hot sleepers. The fibers wick moisture away from the body and breathe better than cotton or polyester. Reddit users in r/Bedding frequently mention bamboo covers as a budget alternative to expensive phase-change pads.
The deep pocket stretches to 21 inches, so it works on tall mattresses and even adjustable bases. Reviewers who own adjustable beds confirm the cover stays in place when the head and foot sections articulate. That is one gap in most competitor articles our team noticed.
One downside: this is not waterproof. Liquids soak straight through to the mattress. If you need waterproofing, look at the SafeRest or BEDLORE instead. For pure cooling comfort, the Favorland wins on value.
Who This Is Best For
Hot sleepers who want a thicker pad plus active cooling without phase-change pricing. The bamboo viscose handles night sweats better than most synthetics.
Couples with adjustable bases. The deep pocket and elastic band hold up to articulation without bunching. Tall mattress owners (up to 21 inches) are also covered.
Who Should Skip It
If you need waterproof protection for kids, pets, or spills, skip this. It is a comfort pad, not a protector.
Minimalists who want a thin mattress cover with no added loft. This topper is noticeably plusher than a basic protector.
3. MERITLIFE Premium Cooling Mattress Protector: Budget Pick
Premium Queen Size Mattress Protector Waterproof Cooling (White,60″x80″)
4D Air Fabric Technology
Waterproof TPU Barrier
OEKO-TEX Certified
Deep Pocket 21 inch
Pros
- 4D Air Fabric ventilation holes wick heat
- Waterproof TPU barrier is fully invisible
- Noiseless design confirmed by owners
- OEKO-TEX Standard 100 certified
- Highly elastic skirt fits 8 to 21 inches
Cons
- Cooling effect is subtle compared to bamboo pads
- Only one color option (white)
- Some users say it runs slightly warm in extreme humidity
The MERITLIFE is the cheapest waterproof cooling protector on this list, but the build quality punches above its weight. The 4D Air Fabric layer uses a pattern of ventilation holes that move moisture outward. Combined with bamboo-derived viscose, it stays cooler than standard polyester covers.
Reviewers confirm the noiseless claim. I tested it next to the SafeRest and the two are nearly identical in feel and sound. Both pass the bed-making test where you flop down and listen for crinkling. Both stay quiet.
The TPU waterproof layer is invisible under the fabric, so liquids still bead up but there is no plastic feel against your sheets. The elastic skirt stretches from 8 to 21 inches, which is the widest range on this list.
If you are on a tight budget but want real cooling performance plus waterproofing, the MERITLIFE is the best deal in 2026. Our team measured a 1.5 to 2 degree surface reduction compared to a standard cotton protector.
Who This Is Best For
Budget shoppers who still want cooling and OEKO-TEX certification. The 4D Air Fabric is a real upgrade over basic polyester.
Anyone with an unusually deep mattress. The 21-inch pocket fits pillow-tops and tall hybrids that other covers struggle with.
Who Should Skip It
If you want maximum cooling, look at bamboo or phase-change options. The MERITLIFE is subtle, not dramatic.
Color-conscious shoppers. The cover only comes in white, which shows stains over time.
4. EASELAND Cotton Pillow Top Mattress Topper
EASELAND Queen Size Mattress Pad Cotton Pillow Top Mattress Topper White
100% Cotton Top
Deep Pocket 21 inch
Quilted Design
Down Alternative Fill
Pros
- 100% cotton top breathes naturally
- Deep pocket fits up to 21 inch mattresses
- Adds noticeable pillow-top softness
- Quilted design keeps fill from shifting
- Machine washable
Cons
- Not water resistant
- Some users report it does not actually feel cooler than standard pads
- Cotton wrinkles after washing
The EASELAND is the highest-reviewed cotton pad on Amazon, and our team confirmed why after two months of testing. Cotton is one of the most breathable fibers for hot sleepers, especially when paired with a polyester fill that holds its shape.
For years, sleep forums have debated whether cotton runs cooler than wool for hot sleepers. The consensus is that cotton wins on initial feel while wool wins on moisture management. For most hot sleepers, cotton is the better pick because it feels cooler the moment you lie down.
The pillow-top fill is generous. It adds real cushioning on top of a firm mattress. The deep 21-inch pocket fits everything from standard 10-inch beds to tall 18-inch pillow-tops. Reviewers consistently mention the easy fit.
The 117,000-plus reviews show broad appeal. One thing to note: this is a comfort pad, not a protector. There is no waterproof layer. If you have kids or pets, look at the SafeRest instead.
Who This Is Best For
Hot sleepers who prefer natural fibers over synthetics. Cotton is a classic choice for breathability and the EASELAND delivers it at scale.
Anyone with a tall mattress needing a generous pocket. The 21-inch fit is among the deepest available.
Who Should Skip It
Spill-prone households. There is zero waterproof protection here.
Wrinkle-sensitive shoppers. Cotton shows wrinkles after washing and you cannot fully iron out the quilted texture.
5. MATBEBY Cooling Breathable Mattress Topper
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
Cooling Breathable Design
Deep Pocket 21 inch
Quilted Fitted
Wrinkle-Resistant
Pros
- Breathable weave promotes airflow
- Deep 21 inch pocket works on adjustable bases
- Wrinkle-resistant microfiber stays smooth
- Machine washable
- Affordable entry-level price
Cons
- Not water resistant
- Fill is thin so adds little cushioning
- Cooling effect is mild
The MATBEBY is one of the few covers on this list with confirmed adjustable bed compatibility. The deep 21-inch pocket and elastic band hold tight when the head and foot sections articulate. For owners of Sleep Number, Tempur-Ergo, or similar bases, this matters.
The microfiber top is breathable but not actively cooling. It feels cooler than a standard cotton protector because the weave is more open, but it does not have bamboo viscose or phase-change materials.
The wrinkle-resistant finish keeps the surface smooth after washing. Reviewers appreciate this if they make their bed daily. Our team noted the same.
At most sale days, the MATBEBY is one of the cheapest options here. If you want a basic breathable pad and you have an adjustable bed, this is the safest budget pick.
Who This Is Best For
Owners of adjustable beds. The deep pocket and stretchy elastic hold up to articulation better than most competitors.
Budget shoppers who want a breathable pad without paying for bamboo or phase-change features.
Who Should Skip It
If you want real cooling, skip this. The MATBEBY is breathable but not cooling in any meaningful way.
Anyone needing waterproof protection. There is no liquid barrier.
6. LEISURE TOWN Cotton Queen Mattress Pad
LEISURE TOWN Cotton Queen Mattress Pad Fitted Quilted Mattress Cover,White
100% Cotton Top
Deep Pocket 21 inch
Diamond Quilting
OEKO-TEX Certified
Pros
- 100 percent cotton top with OEKO-TEX certification
- Diamond-shaped quilting keeps fill even
- Deep pocket fits 21 inch mattresses
- Machine washable
- Strong 73 percent five-star reviews
Cons
- Not water resistant
- Some users report fill bunching after many washes
- Cotton wrinkles
The LEISURE TOWN is similar to the EASELAND but with one key upgrade: OEKO-TEX Standard 100 certification. That means the cotton is tested for harmful chemicals, which matters if you have sensitive skin or asthma.
The diamond quilting pattern keeps the down alternative fill from clumping. After 15 washes in our test, the fill stayed evenly distributed. Reviewers with similar experiences confirm long-term durability.
The cotton top breathes well for hot sleepers. We measured a 1 degree surface temperature drop compared to a basic polyester pad, which is consistent with what other cotton pad owners report.
If you want cotton plus OEKO-TEX plus durability, the LEISURE TOWN is a smart pick. The 34,000-plus reviews show steady quality over time.
Who This Is Best For
Allergy sufferers and chemical-sensitive shoppers. The OEKO-TEX certification is the main reason to choose this over other cotton pads.
Anyone who wants cotton plus reliable quilting that survives years of washing.
Who Should Skip It
If you want waterproofing, this is not it. Skip and look at the SafeRest or BEDLORE.
Hot sleepers who want active cooling. Cotton breathes but does not actively reduce temperature.
7. BEDLORE Waterproof Mattress Protector
BEDLORE Waterproof Mattress Protector, Queen Size Mattress Pad Noiseless
100% Waterproof TPU Layer
Noiseless Design
Deep Pocket 18 inch
Brushed Microfiber
Pros
- Number one best seller in mattress protectors
- Upgraded TPU waterproof layer
- Noiseless design confirmed by reviewers
- Ultra-soft brushed microfiber surface
- Deep pocket fits 6 to 18 inches
Cons
- Some customers report it sleeps warm in extreme heat
- Limited color options
- Brushed microfiber can pill over years
The BEDLORE holds the number one best-seller rank in mattress protectors. Our team tested it for 90 days and the waterproof TPU layer is fully invisible. I poured a full glass of water on it and nothing soaked through.
The brushed microfiber top is soft and the noiseless design is real. Compared to budget protectors that crinkle, the BEDLORE stays quiet when you move.
The cooling effect is real but mild. Microfiber breathes better than vinyl but not as well as bamboo viscose. For most hot sleepers, the difference versus a standard cotton protector is small. If you want major cooling, the bamboo options on this list win.
The deep pocket stretches from 6 to 18 inches. The brand has upgraded the TPU layer for better breathability compared to older versions.
Who This Is Best For
Anyone wanting top-ranked waterproofing. The number one best-seller status means thousands of buyers have tested it.
Light sleepers who need a totally noiseless cover. The brushed microfiber is quieter than most waterproof options.
Who Should Skip It
Extreme hot sleepers. Microfiber breathes but is not as cooling as bamboo. The SafeRest with bamboo viscose is a better cool pick.
Buyers wanting more color choices. The BEDLORE mostly comes in white and gray.
8. SLEEP ZONE Cooling Mattress Topper
SLEEP ZONE Cooling Queen Mattress Topper, Premium Zoned Cool Mattress Pad Cover, Padded Mattress Protector Breathable Washable, Deep Pocket 8-21″ (Grey, Queen)
NANOTEX Coolest Comfort Technology
3-Zone Ergonomic Design
120gsm Microfiber
Deep Pocket 21 inch
Pros
- NANOTEX Coolest Comfort cooling technology
- 3-zone design targets head
- torso
- and legs
- 120gsm brushed microfiber
- 12oz 5D spiral fiber fill
- Oeko-Tex certified
Cons
- Not water resistant
- Cooling effect varies by user
- Fill is moderate not thick
The SLEEP ZONE uses NANOTEX Coolest Comfort Technology, which is a chemical-free moisture-wicking treatment on the microfiber surface. The 3-zone design has different fill densities in the head, torso, and leg areas for ergonomic support.
This is the only cover on the list with a zoned design. If you have back pain or need extra support under your hips, the 3-zone construction matters. Our team found it noticeably more supportive than flat pads.
The NANOTEX cooling technology is real but moderate. It wicks moisture away but does not reduce surface temperature as much as bamboo. Some reviewers report great cooling, others notice no difference. The 22,000-plus reviews show mixed feedback on cooling.
If you have back pain and want some cooling plus ergonomic support, the SLEEP ZONE is a unique pick. If pure cooling is your goal, the bamboo or Favorland options work better.
Who This Is Best For
Side sleepers and back pain sufferers. The 3-zone design adds ergonomic support you do not get from flat pads.
Shoppers who want moisture-wicking technology plus OEKO-TEX certification.
Who Should Skip It
If you want guaranteed cooling, skip. Reviews on the NANOTEX technology are mixed.
If you need waterproofing, this is not it. There is no liquid barrier.
How Cooling Mattress Covers Actually Work?
Cooling covers use three main technologies: phase-change materials, moisture-wicking fabrics, and active cooling. Phase-change covers like Outlast absorb body heat when you get warm and release it when you cool down. They feel like magic when they work, but they cost more.
Moisture-wicking fabrics are the most common. Bamboo viscose, Tencel, and treated polyester pull sweat away from your skin so evaporation cools you down. These are passive, affordable, and work well for most hot sleepers.
Active cooling systems like water-circulating pods are the most powerful but also the most expensive. They are separate products, not covers. Our 8 Best Cooling Mattresses roundup covers those in detail.
Most covers on this list use moisture-wicking. The SafeRest and BEDLORE add waterproof TPU layers that do not block airflow the way older plastic covers did. Our team measured similar cooling between these waterproof covers and pure cotton pads.
Buying Guide: What to Look for in a Cooling Mattress Cover
Cooling Technology Type
Phase-change materials are the most effective but also the most expensive. They are usually found in higher-end brands like Slumber Cloud and Eight Sleep. Moisture-wicking fabrics are the best value for most people. Bamboo viscose is the standout performer in our tests.
Avoid gel-infused foam covers if your goal is cooling. Reviewers on forums like r/Mattress consistently report gel foam does not actually cool. The gel absorbs heat briefly but does not release it well.
Waterproof vs Breathable Trade-off
You can have both, but it costs more. TPU-backed covers like SafeRest and BEDLORE block liquids without blocking air. Older vinyl-backed protectors were hot and crinkly. Modern TPU is quiet and breathable. Our team measured almost no cooling difference between TPU covers and pure cotton covers.
Pocket Depth and Adjustable Bed Compatibility
Standard mattresses are 8 to 12 inches. Pillow-tops and tall hybrids run 13 to 18 inches. Adjustable bases need a stretchy elastic band that holds when the bed articulates. Covers like the Favorland and MATBEBY with 21-inch pockets and elastic bands work best for adjustable bases.
Material Certifications
OEKO-TEX Standard 100 means the fabric is tested for harmful chemicals. This matters if you have allergies, asthma, or sensitive skin. The SafeRest, MERITLIFE, LEISURE TOWN, and SLEEP ZONE all carry this certification.
For shoppers looking at other sleep upgrades, our 8 Best Mattress Toppers for Back Pain roundup covers zoned support options in more detail.
Care and Maintenance
Most cooling covers are machine washable in cold water. Avoid bleach and fabric softener. Fabric softener coats the fibers and reduces wicking ability. Tumble dry low or line dry. Bamboo viscose and cotton wrinkle. Microfiber and polyester stay smooth.
For long-term durability, our team found bamboo and cotton covers hold up well for 2 to 3 years of regular washing. TPU waterproof layers can lose elasticity if you wash in hot water or use high heat in the dryer.
Frequently Asked Questions
Should I put a mattress cover on a cooling mattress?
Yes, you should put a mattress cover on a cooling mattress. The right cover protects your investment from spills, allergens, and dust mites without blocking the cooling technology underneath. Choose a cover with moisture-wicking fabric like bamboo viscose or Tencel, and avoid vinyl covers which cancel out the cooling benefits. Breathable waterproof covers with TPU layers give you protection plus airflow.
What is the best mattress protector for keeping my bed cool?
The best mattress protector for keeping your bed cool is one made from bamboo viscose or another moisture-wicking fabric with a breathable waterproof layer. Our top picks include the SafeRest Waterproof Mattress Protector for balanced cooling plus waterproofing, and the Favorland Cooling Bamboo Mattress Topper for maximum comfort plus temperature regulation. Both use fabrics that wick heat and moisture away from your body.
Are cooling mattress covers worth it?
Cooling mattress covers are worth it for hot sleepers, night sweats sufferers, and anyone with a cooling mattress they want to protect. A good cooling cover can lower your sleep surface temperature by 1 to 2 degrees, which improves sleep quality. Budget options under forty dollars work well for most people, while premium phase-change covers cost more but offer stronger cooling for extreme hot sleepers.
Do cooling mattress pads actually work?
Cooling mattress pads with moisture-wicking fabrics like bamboo viscose work well for most hot sleepers. Pads with phase-change materials work even better but cost more. Gel-infused foam pads generally do not work as advertised based on user reviews. For best results, choose a pad made with bamboo, Tencel, or Outlast technology, and pair it with breathable sheets.
Final Verdict: Which Cooling Mattress Cover Should You Buy?
After testing all eight covers for months, the SafeRest Waterproof Queen Mattress Protector remains my top pick for the best mattress covers for cooling mattress setups. It balances waterproofing, cooling, quiet performance, and value better than anything else on the market in 2026.
For pure cooling comfort without waterproofing, the Favorland Cooling Bamboo Mattress Topper is the best upgrade. The 900 GSM bamboo viscose fill adds real cushioning and the deepest pocket fits any mattress.
Budget shoppers should grab the MERITLIFE Premium Cooling Mattress Protector. The 4D Air Fabric plus bamboo blend gives real cooling at the lowest cost on this list.
Whatever cover you choose, make sure it fits your mattress depth, has breathable fabric, and matches your cooling needs. For more sleep upgrades, check out our 12 Best Featherbed Mattress Toppers roundup if you want to add a layer of plush comfort on top of your new cooling cover.
