Serta® Cool Relief™ 4-Inch Pillow Top and Gel Memory Foam Mattress Topper, Assorted Sizes

Restore Your Mattress with Premium Cool Comfort

If your mattress runs hot, the Serta® Cool Relief™ 4-Inch Pillow Top Gel Memory Foam Mattress Topper is the upgrade you've been waiting for. Designed with dual action cooling, it works on two levels simultaneously: a cool-touch cover that delivers instant relief the moment you lie down is paired with gel-infused memory foam, which provides continuous cool comfort throughout the night. Together, they create a cooler sleep environment from the first minute to the second you wake up.

The Perfect Balance of Cool Comfort and Support

Luxury sleep is about balance, and this topper is crafted to achieve it. The 1-inch pillow top adds plush cushioning with a refreshing feel, while 3 inches of gelinfused memory foam contour to your body. The memory foam relieves pressure and supports natural alignment, helping to reduce tossing and turning for undisturbed sleep. Cooling gel helps to reduce heat, regulating a more comfortable sleep temperature. The result is a sleep surface that's supportive, comfortably plush, and noticeably cooler than the mattress alone.

Machine Washable Cover

The Serta® Cool Relief™ 4-Inch Mattress Topper includes a removable, cool-touch pillow top cover that is machine washable and dryable. It stretches like a fitted sheet to cover up to a 17-inch deep mattress and prevents your topper from sliding.
