xSleep cooler and more comfortable with ThermaGel technology
Elevate your nights with the Serta ThermaGel Cooling Memory Foam Mattress Topper. This 3-inch layer sits atop your existing mattress to deliver a breathable, contouring surface that adapts to your body. Gel-infused memory foam works with your natural sleep movements, helping relieve pressure while keeping the surface refreshingly cool through the night. Designed for versatility, it fits atop most standard mattresses, turning an ordinary bed into a personalized sanctuary where warmth and motion are balanced by breathable comfort.
What makes this topper stand out is its Thermally aware design. ThermaGel particles work to draw heat away from the body, creating a cooling effect that can help hot sleepers feel more at ease as sleep unfolds. The result is a surface that responds to your shape—soft where you want it and supportive where you need it—without sacrificing breathability. The topper is a practical upgrade that can soften a firm mattress, help align joints, and extend the life of your current bed by providing an extra layer of protection against wear.
