Cooling Mattress Pads That Work: Tested Picks for Hot Sleepers

Compiled by the editorial desk based on hands-on testing by staff writers and contributors, with reference to product specifications and tester experiences.

For those who regularly wake up drenched in sweat, a cooling mattress pad can be a game-changer. After testing over 60 models from brands like The Company Store and Slumber Cloud, our editors have identified seven that consistently deliver relief. The key differentiator? Thickness. Thinner pads cool faster but offer less support, while thicker pads provide more cushioning but may retain heat.

Top Picks at a Glance

Our best overall is The Company Store Cool Zzz Mattress Pad ($129), which impressed tester Cheryl with its plush, hotel-like feel and effective cooling. For budget-conscious shoppers, the Sleep Zone Cooling Mattress Topper ($43) offers breathable comfort at a fraction of the cost. Those battling night sweats might prefer the Slumber Cloud Performance Mattress Pad ($237), which kept tester Katy cool even when her AC broke. The Whisper Organics 100% Cotton Organic Mattress Pad ($187) is the most breathable option, while the Helix GlacioTex Mattress Protector ($249) is waterproof and cool to the touch. The Serta Power Chill Mattress Protector ($49) is a slim, affordable choice, and the GhostBed Memory Foam Topper ($329) adds extra support with cooling gel-infused foam.

How We Tested

Our testers slept on each pad for at least a month, evaluating cooling effect, fit, comfort, and value. We noted how well pads stayed in place on deep mattresses, whether they flattened over time, and how they performed after washing. Long-term testing continues, with updates planned at three and six months.

What to Consider Before Buying

Understanding the difference between a mattress pad and a topper is crucial. Pads are thinner, designed to protect the mattress with minimal cushioning, while toppers add significant padding, often foam, which can trap heat. However, some toppers, like the GhostBed, use gel-infused foam to stay cool. Materials matter: Tencel and cotton are breathable, while polyester is comfortable but less cooling. Look for features like deep pockets and secure elastic to ensure a snug fit.

Our testers found that the right pad can transform sleep quality. Cheryl, who suffered from hip discomfort, now enjoys a luxurious feel with the Company Store pad. Jocelyn, a combination sleeper who tends to overheat, appreciated the Sleep Zone's breathability. Katy, who usually wakes up hot, praised the Slumber Cloud's temperature regulation. Jennifer, who disliked bulky toppers, loves the Whisper Organics' lightweight design. Our Helix tester, who sleeps with a partner, noted the waterproof protection and cooling effect. Michele, a side sleeper, uses the Serta pad in summer for extra cooling. Lisa, a side sleeper with a firm split-king mattress, found the GhostBed topper provided the plushness she needed.

While individual results vary, these seven options stood out in our testing for their ability to keep sleepers cool and comfortable. Whether you prioritize budget, breathability, or extra support, there's a cooling mattress pad here to suit your needs.
