Why you should trust this review
Mattress covers are one of the most heavily marketed sleep products with some of the weakest performance claims. We cut through the noise by testing 11 covers under controlled conditions, using two testers with different heat sensitivity levels sleeping on the same mattress base across identical nights.
We measured surface temperature at the start, middle, and end of each sleep session, and we specifically tested whether waterproof backing materials negated the cooling benefit of the top layer. We also laundered each cover five times to check whether cooling properties held up over repeated washing.
How we tested cooling mattress covers
All covers were fitted on the same queen innerspring mattress in a room held at 70 degrees Fahrenheit. Testers wore standard pajamas and used the same sheets for consistency. We used a FLIR thermal camera in addition to spot thermometers to get a full surface temperature map rather than a single point measurement.
We noted any noise or texture issues, since some waterproof covers crinkle during movement. Every cover that is marketed as waterproof was tested with a controlled liquid spill to verify the protection claim.
Who should buy a cooling mattress cover?
People who want to improve their mattress temperature without spending on a new mattress or topper will get the most value here. Cooling covers are also ideal for allergy sufferers who need mattress protection and want cooling properties in the same product.
Couples who share a mattress and have different temperature preferences can benefit by using a cooling cover in a split configuration. Some models are sold in half-queen sizes specifically for this purpose.
Nest Bedding Cooling Mattress Protector: our top pick
The Nest Bedding Cooling Mattress Protector uses a Tencel fabric surface that is inherently moisture-wicking and cool to the touch, backed with a waterproof membrane that is notably quieter than the plastic-feel barriers used in many competing products. In our thermal imaging tests it showed the most even heat distribution across the entire sleeping surface.
It fits mattresses up to 18 inches deep, which accommodates most pillow-top and Euro-top designs. The fitted skirt stayed in place through seven nights of active testing. Care instructions allow machine washing in cold water and low-heat drying, and we confirmed that cooling performance remained consistent after five wash cycles.
At $129 for a queen it sits in the mid-range of the market, but it is the best overall package we tested when you account for cooling performance, waterproofing, noise level, and care convenience.
SafeRest Premium Cooling: best value option
The SafeRest Premium Cooling Mattress Protector brings genuine terry cotton surface texture and waterproof backing at around $59. It does not use phase-change technology but the terry weave creates micro-airflow pockets that meaningfully improve breathability over standard covers.
In our tests it reduced surface temperature by an average of 1.8 degrees Fahrenheit compared to sleeping on an unprotected mattress. This is less than the 3 to 5 degrees the top performers achieved, but at less than half the price it is a solid value for those who run only moderately warm.
What to look for in a cooling mattress cover
The material science matters. Tencel (lyocell) fabric is naturally temperature-regulating and moisture-wicking. Phase-change material infusions go further by actively absorbing heat when your body temperature rises. Avoid covers that list “polyester cooling fabric” without further specification, since standard polyester does not cool.
Noise is a hidden quality factor. Test any waterproof cover by pressing and moving your hand across it in a quiet room before committing. If it crinkles audibly it will likely disrupt light sleepers. Pocket depth should match your mattress with at least two inches of margin for a secure, non-shifting fit.
Frequently asked questions
What is the difference between a mattress cover and a mattress pad?+
A mattress cover is a thin fitted sheet that primarily protects the mattress. A mattress pad adds a layer of cushioning material on top of the mattress. Both can include cooling technology.
Do cooling mattress covers work on memory foam?+
Yes, but results depend on the technology. Phase-change material covers work best on memory foam because they actively absorb and release heat at the surface level.
Can a cooling mattress cover replace a cooling mattress?+
For mild to moderate heat buildup it can be a sufficient fix. For severe hot sleepers or very warm climates, a full mattress upgrade may still be needed.
How do I know if my mattress cover has true cooling technology?+
Look for Outlast phase-change material, copper or graphite infusion, or active cooling systems. The word 'cooling' alone without a specified technology is usually a marketing claim.
