Waking up in a sweat-soaked sheet is miserable. A cooling mattress protector stops that by adding a breathable, heat-drawing layer between you and the mattress — without the crinkle or plastic feel of old-school covers. The right one keeps you dry, guards your mattress from spills, and still feels like normal bedding.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Here is how to pick the best cooling mattress protector for your bed, based on fabrics that wick moisture, waterproof barriers that stay quiet, and fits that don’t slip.
Our Picks at a Glance
How To Choose The Best Cooling Mattress Protector
Not every “cooling” protector works the same way, so you need to know what you’re buying. Some feel cool for a few seconds when you touch them; others actively pull heat and sweat away all night. The real difference depends on the fabric and the waterproof layer underneath, so check both before you choose.
Start with the surface fabric
Fabric is what your skin touches, so it drives the cooling feel. Bamboo viscose and Tencel (a fiber made from eucalyptus) are the top choices for hot sleepers because they breathe and wick moisture. Cotton is natural and absorbent but can hold sweat. Nylon and spandex blends feel cool to the touch but trap heat for some sleepers. Match the fabric to how hot you actually run at night.
Check the waterproof barrier, not just the top
A truly waterproof protector needs a solid backing layer. The best ones use TPU (a soft, flexible plastic) that blocks liquids without crinkling. Cheaper protectors use a stiffer plastic that feels noisy and traps heat. If you need protection from kids, pets, or spills, the barrier is just as important as the cooling top.
Measure your mattress depth
Protectors fit like fitted sheets, so the skirt must stretch over your mattress. Most standard protectors fit up to 18 inches deep, but thicker pillow-top and hybrid mattresses need 21-inch or 22-inch pockets. Corner straps or fully banded elastic keep the protector from bunching as you move.

In-Depth Reviews
1. SafeRest Waterproof Queen Size Mattress Protector
Our pick — over 4.5★ from 280,000+ verified ratings; the strongest balance of quality and price.
The crowd favorite that quietly solved hot sleep for over a quarter-million owners.
The SafeRest is the pick most people should start with, and the proof is in the sheer volume of happy owners. Its surface is a blend of 60% polyester and 40% viscose derived from bamboo, which gives it a smooth, cool-to-the-touch feel that buyers report sleeps comfortably without the crinkle or heat buildup of typical waterproof covers. The deep-stretch skirt fits mattresses up to 18 inches, so it grips thick pillow-tops snugly and stays put through the night.
Owners mention the quality and fit win people over, and durability is a repeated-purchase legend. One owner reports it lasted 3 years before replacement. Water resistance gets more mixed feedback here than on some rivals: many find it super waterproof, while a smaller group says it isn’t fully. For heavy-duty bed-wetting or senior-pet scenarios, the GOPOONY below is the safer bet.
It’s OEKO-TEX Standard 100 certified, meaning it’s been tested for harmful substances. Machine-washable with no zippers and no added padding, it’s a fitted style that blends into your bed rather than standing out.
What wins people over
- The quality is the top praise — over 30,000 owners single out build and feel
- Fit is the second most-loved trait, with 13,000+ highlighting how snugly it sits
- Quiet, no-crinkle surface that doesn’t trap heat like plastic-backed covers
What to check first
- Water resistance is genuinely mixed — light spills are fine, heavy soaking is not guaranteed
- Fits up to 18 inches, so extra-thick 21-inch mattresses are a stretch
The default pick for: anyone who wants a proven, comfortable, budget-friendly cooling layer that handles everyday sweat and the occasional spill.
Think twice if: you need guaranteed heavy-duty waterproofing for bedwetters or pets — that’s the GOPOONY’s job.
2. GOPOONY Premium Waterproof Mattress Protector California King
The deep-pocket champion that swallows 21-inch mattresses whole and shrugs off pet accidents.
If you have a thick mattress or real waterproofing needs, the GOPOONY is the value pick to beat. The surface is a bamboo viscose blend (60% polyester, 40% viscose made from bamboo) that’s soft, skin-friendly, and good at wicking moisture.
The backing is premium TPU (a soft, flexible plastic), which is the key difference: it blocks sweat, bed-wetting, liquids, and stains while staying breathable and noiseless. Customers note the waterproofing is the real deal — One owner’s senior cat urine produced “zero soak-through,” and the protector stayed leak-proof after multiple washes. It also held up to baby and child accidents without a drop reaching the mattress.
At 3.2 pounds, it’s substantial but not bulky, and owners say it works comfortably as a fitted sheet. The honest note: some find it runs slightly warmer than expected and takes longer to dry after washing, so it’s a protection-first choice rather than the coolest option here.
Built for protection: quality is the top praise, with fit close behind — owners consistently call it durable, stretchy, and noiseless.
The trade-off: it’s not the coolest surface on this list; think “comfortable and bulletproof” rather than “ice-cold.”
Reach for this if: you have a deep 21-inch mattress or need serious, proven waterproofing for kids, pets, or spills.
Look elsewhere if: cooling is your #1 priority and protection is secondary — the PUREgrace or Bedgear run cooler.
3. Unikome Soft Cooling and Waterproof Queen Mattress Topper
A five-layer build that claims real temperature relief and backs it with an aggressive fit system.
The Unikome takes the cooling claim seriously on paper. It’s built with five layers: a breathable cooling microfiber top to dissipate heat, soft blended filling for lightweight support, a sturdy waterproof TPU layer, and quiet knit fabric. The manufacturer claims the fabric can reduce skin temperature by 3-5°F, a specific number most rivals avoid.
Fit is where it goes above and beyond — the 360-degree full-wrap design and deep pockets accommodate mattresses from 8 to 21 inches thick, and the 1.6-inch high-elastic straps are extra-wide to prevent slipping. Owners praise how easily it installs and how well it stays put, even on adjustable hospital beds. The top fabric is 90% cooling nylon and 10% spandex, which explains the cool-touch feel.
Here’s the honest catch: the cooling effect gets mixed reviews. Some owners love it, while others say the bed feels warmer. One buyer’s verdict — “it is soft and comfy” but the photos are “blatant false advertisement” on thickness — sums up the consensus: this is a comfortable, well-fitted protector, not a miracle cooling pad. If you run very hot, the PUREgrace or Bedgear are more reliable bets.
The thing everyone raves about: comfort and softness top the praise list, with fit close behind — the straps are the standout feature.
Keep expectations in check: cooling is genuinely mixed, so buy this for the comfort and secure fit, not the chill factor.
Best for: side sleepers and combo sleepers who want a soft, slip-free layer on a deep mattress with decent waterproofing.
Not for: anyone who expects a dramatic temperature drop — treat the 3-5°F claim as a maybe, not a guarantee.
4. Serta Power Chill Cooling Waterproof Mattress Protector, Full
The 90-year bedding name that brings genuinely reliable waterproofing and a cool-touch knit.
Serta brings brand weight to the protector aisle, and for buyers who’ve been burned by no-name covers, that matters. The Power Chill uses Cool-Hex technology — a cool-to-touch knit fabric made from nylon and spandex — designed to turn heat into cooling comfort. It’s luxuriously soft and, as one owner put it, “as soft and quiet as cloth” with no crinkle or stiffness under the top sheet.
Waterproofing earns rare praise here: One buyer’s fifth purchase across beds, calling it “one of the ONLY brands… actually waterproof,” with zero leaks on bedwetting duty. The 3M Scotchgard treatment (a stain-resistant coating) helps stains wash out easily and inhibits odor growth. The elastic skirt fits traditional and foam mattresses up to 15 inches deep, and the Full size measures 54 x 75 inches, so it stays put on your bed.
The honest limitation: cooling is mixed, with roughly as many owners saying it keeps them cool as saying it makes them hotter at night. It’s also a fitted-sheet style that covers only the top and sides, not a full encasement. For a hot sleeper seeking dramatic relief, this is a solid but not spectacular choice; for waterproof reliability from a trusted name, it’s excellent.
The standout: proven waterproofing that owners repeatedly buy again — the brand trust is earned here.
Know the fit: 15-inch depth limit and top-and-sides coverage mean it’s not for very thick mattresses or full encasement needs.
Who it suits: buyers who prioritize reliable waterproofing and a soft, quiet surface from an established bedding brand.
Who should skip: hot sleepers expecting a true cooling effect, or anyone with a mattress deeper than 15 inches.
5. Sealy Cool Cotton Moisture-Wicking 100% Cotton Mattress Pad Queen
The cotton purist’s pick that proves natural fabric can beat plastic-backed heat.
If you hate the synthetic feel of most protectors, the Sealy Cool Cotton is a breath of fresh air — literally. Its cover is a luxuriously soft 300-thread-count made of 100% cotton, which is a genuinely different proposition from the nylon and polyester blends everywhere else. One owner who gets hot easily put it plainly: “I thought with it being cotton it would make me sweat, but it does not.”
The cooling here comes from moisture-wicking technology rather than a cool-touch coating. The pad pulls sweat away from your body and releases it, keeping you cool and dry through the night. It’s also hypoallergenic, with an Eternaloft polyester fill that makes it a comfortable option for people with down allergies. The fitted skirt stretches over corners and fits queen mattresses up to 18 inches deep.
The key difference from other picks: this is not fully waterproof. It has stain-release protection that helps spills wash out easily, but it’s a moisture-wicking pad, not a waterproof barrier. One owner who switched from a plastic-backed pad noted the improvement in sleep quality immediately — no more heat buildup, no more slipping sheets. If you need a true liquid barrier, pair this with a dedicated protector or choose the SafeRest instead.
The selling point: pure 100% cotton comfort that stays cool and stops sheets from sliding, per owner reports.
The honest limit: fit gets mixed feedback — some love it, others find it runs loose — and it’s not a waterproof shield.
Choose this for: cotton lovers and hot sleepers who want natural breathability and don’t need heavy-duty waterproofing.
Avoid it if: you need a guaranteed liquid barrier for kids or pets — this pad handles moisture, not floods.
6. PUREgrace Queen Mattress Protector – Cooling Eucalyptus Tencel Fiber
The eucalyptus-fiber luxury layer that stays soft, quiet, and locked in place all night.
The PUREgrace is the premium pick for hot sleepers who want a fabric that actively works while they sleep. Its surface is 100% Tencel eucalyptus fiber — a natural material praised for breathability and airflow promotion, designed to keep your sleep environment comfortable rather than just feeling cool for a moment. Owners consistently describe it as soft, cushy, and quiet, with no crinkle noise and no change to the mattress feel.
What separates this from cheaper options is the construction. The reinforced corner safety straps and deep-pocketed corners keep the protector smooth and in place through the night, even on adjustable bases — a feature owners specifically call out. Behind the soft Tencel top sits a thin, quiet, 100% waterproof barrier that protects against spills, sweat, and everyday moisture while staying flexible. It’s machine washable and dryer safe, with One owner notes durability after 2 years of regular washing.
The 10-year warranty and owner reports of surviving vomiting incidents and repeated washes back the maker’s confidence. The trade-off is the price, which sits above most rivals here. But for a hot sleeper who wants premium fabric, real waterproofing, and straps that actually work, the PUREgrace justifies the cost.
Why it earns the premium
- Softness is the #1 praise — 54 owners single out the Tencel feel
- Fit ranks second, with the corner straps and deep pockets keeping it taut
- Quiet, non-plastic waterproof layer that washes well
The honest trade-off
- It’s the most expensive pick here — budget buyers can get 80% of the feel for less
- Some owners note it’s slightly warmer than expected for a “cooling” product
Worth the splurge for: hot sleepers who want a natural, breathable Tencel surface with genuine waterproofing and straps that never slip.
Pass if: you’re on a tight budget or simply need basic protection without the luxury fabric.
7. OLANLY Queen Bamboo Viscose Cooling Mattress Topper
The cushioning upgrade that turns a firm, aging mattress into a near-new sleep surface.
The OLANLY is a different animal from the protectors above — it’s a true topper with a pillow-top profile, built to add softness to a mattress that feels too firm, flat, or uncomfortable. The surface is 40% rayon derived from bamboo and 60% polyester, chosen to promote airflow and reduce heat buildup. That makes it a comfortable option for hot sleepers who want a softer feel without the dense, heat-trapping sensation of traditional foam toppers.
The real star is the down-alternative fill, which gently cushions pressure points like the shoulders, hips, and back. Owners describe it as feeling like sleeping on a new mattress — One parent upgraded a 15-year-old mattress to near-new feel, and another reported relief for a partner’s achy joints. The stretchable deep-pocket skirt with straps keeps it secure, even stopping sheets from sliding on slippery foam mattresses.
Two honest caveats. First, thickness gets mixed feedback — several owners note it’s not as thick as advertised, so manage expectations on the “pillow-top” claim. Second, this is not a waterproof protector; it’s a comfort topper, so pair it with a real protector if you need a liquid barrier. The cooling effect is also mild, with owners describing it as “works slightly” rather than dramatic.
What wins people over: softness tops the praise list, with fit close behind — owners love how it stays put and cushions pressure points.
The honest note: buy this for added softness and breathability on a firm mattress, not for waterproofing or dramatic cooling.
Best for: side and back sleepers on firm mattresses who want a soft, breathable cushion layer without buying a new bed.
Not for: anyone needing waterproof protection or expecting a thick, lofty topper.
8. Bedgear Dri-Tec Waterproof Mattress Protector Queen
The performance-fabric specialist that married serious moisture-wicking with serious waterproofing.
Bedgear built its name on performance sleep gear, and the Dri-Tec shows why. The surface uses Dri-Tec moisture-wicking fabric — an advanced performance textile that pulls moisture away from the body and disperses it for faster evaporation, helping keep your sleep surface cool and dry. This is active cooling through fabric engineering, not just a cool-touch coating, which is why owners who run hot tend to trust it.
The waterproofing is the quiet kind: a protective layer shields your mattress from spills, sweat, stains, and moisture while maintaining a soft, noiseless surface. An 8-year owner calls it the only pad they trust, with wine and urine never reaching the mattress. The fully banded elastic stretches to fit mattresses up to 18 inches deep with a fitted-sheet style grip that stays securely in place.
Here’s the rub: at the highest price in this lineup, value gets mixed feedback. Some owners consider it worth the money and expect it to last years; others find it pricey and raise durability concerns. The quality itself is the most-praised trait, with fit second. If you’re willing to pay for a performance-grade protector that handles both heat and heavy accidents, this is the one; if budget matters more, the SafeRest or GOPOONY deliver similar core protection for less.
The performance edge: quality is the top praise, with fit second — owners consistently vouch for the moisture-wicking and waterproof combo.
The honest caveat: value is genuinely mixed at this price point, and a few owners question long-term durability.
Splurge on this if: you’re a hot sleeper who also needs serious waterproofing and wants a performance-grade fabric that does both.
skip it if: you want the same core protection for less money — the SafeRest covers the basics at a friendlier cost.
Understanding the Specs
TPU vs. plastic waterproof layers
TPU (thermoplastic polyurethane) is the soft, flexible plastic used in quality waterproof protectors. It blocks liquids completely but stays quiet and flexible, so you don’t hear crinkling when you roll over. Cheaper protectors use stiffer plastic that traps heat and makes noise. If a protector doesn’t name its backing material, assume it’s the crinkly kind.
Cooling fabrics: what actually works
Bamboo viscose and Tencel (a eucalyptus-based fiber) are the most reliable cooling surfaces because they promote airflow and wick moisture. Nylon and spandex blends feel cool to the touch instantly but can trap heat for some sleepers. Cotton is natural and breathable but can hold sweat. The “cool-touch” claim often means a brief sensation, not all-night temperature control.
