The Serenity by Tempur-Pedic 3-inch memory foam mattress topper transforms any existing mattress with premium comfort and support. Featuring 3 inches of Tempur Material originally developed by NASA to absorb G-forces for astronauts, this topper continuously adapts to your body's weight, shape, and temperature to alleviate pressure points that cause tossing and turning.

The topper includes a breathable performance cover made from a soft polyester blend knit fabric designed for temperature regulation and enhanced breathability. The removable cover is machine washable and dryable for easy maintenance, and the stretch-knit skirt provides a secure fit on mattresses up to 17 inches deep. The medium-feel memory foam construction is hypoallergenic and designed to relieve shoulder and arm aches while reducing numbness and tingling in extremities during sleep.

Designed and assembled in the USA from domestic and imported materials, this topper delivers the one-of-a-kind Tempur technology that helps upgrade the comfort and support of any mattress without the cost of purchasing a completely new bed.
