Enjoy refreshing and renewing sleep every night with a Sealy Posturepedic Copper Cushion Firm Full mattress. In the top half of the mattress, layers of gel memory foam offer body-conforming comfort and reduced motion transfer. The bottom half of the mattress offers Sealy's premium version of our specially engineered encased coil. Encasing allows each coil to move independently, for more targeted support and reduced motion transfer. This mattress combines both innerspring support and contouring foam for a hybrid sleep environment you'll look forward to every night.
