Pressus ThermoRest - Cooling Mattress Topper
Stop Waking Up in a Sweat
This quilted topper blends bamboo viscose with polyester so heat moves away from your body instead of getting trapped against it. The fitted skirt stretches to grip mattresses up to 18 inches deep, so it stays in place all night instead of sliding or bunching. Two inches of cushioning softens pressure points without the sinking feeling of a firm mattress, and the whole thing goes straight in the washing machine.
