Sleep like you’ve never slept before with the Serta ThermaGel Cooling Memory Foam Mattress Topper, a 2-inch, queen-size layer designed to sit atop virtually any mattress. As part of Serta’s family of comfort solutions, this topper blends body-conforming memory foam with ThermaGel beads to help balance the night-time temperature and deliver a softer, yet supportive feel under a blue-toned cover.

Cool Comfort That Stands Up to the Night

ThermaGel beads embedded in the foam actively regulate surface temperature, creating a cooler sleeping surface for longer stretches. The open-cell design promotes airflow, so you feel less trapped heat as you move through the night.
