Add A Comfort Layer Add extra comfort to your current mattress. Made from temperature-sensitive Memory Foam and Polyfoam, the 2" Harmony Topper has exceptional cushioning and superior pressure relief that will reduce tossing and turning when you sleep. Unpack the mattress topper and lay it on the top of your mattress and begin enjoying the benefits of a good night's sleep. Your body’s weight is distributed evenly along the surface, relieving pressure and helping you to sleep more soundly without tossing and turning. Memory foam mattress toppers are great for use in dorm rooms, guest bedrooms, or improving the feel of old mattresses. This topper is built with a rubber, non-slip backing so it doesn’t move during sleep.
