It's time to start shopping for a new alarm clock, because you'll be sleeping deeply from now on when you're lying on the Comfort Sleep Supreme Gel Sculpted Mattress Topper with Waterproof Cover. Using the NASA-designed Memory Foam, this thick mattress pod features a double-sided design that pairs Memory Foam with a rejuvenating gel to reduce motion transfer, relieve pressure and reduce heat while sleeping. The sculpted top helps channel away warm air, and the double-sided design lets you choose a smooth or textured side for your sleeping surface. You'll sleep easy while the breathable cover of polyester knit fabric acts as a barrier against moisture. This topper is offered in California King, Full, King, Queen, and twin sizes.
