The Sealy Posturepedic Hybrid Copper plush features a Zoned Sealy Embrace Premier Coil system. These coils are individually encased and are better suited at providing contoured support no matter your size or shape. The “Zoned” feature is also designed to improve the support and comfort you receive from this mattress by increasing the coil count toward the middle of the mattress. This coil system, along with the CoreSupport Center provides unprecedented support for the middle third of the mattress right where the majority of your body weight will be. The Sealy Posturepedic Hybrid Copper pairs amazingly with Sealy’s Reflexion UP adjustable base that is built to fit within most standard beds. The UP base gives you the ability to raise the head of your mattress up or lower it to suit your comfort needs. You are able to raise your head up to about a 65 degree angle. The wired remote provides simple and effortless control over the motion of the bed. The UP is designed to be placed directly in standard bed frames, replacing the box spring. King and California King sizes feature a split base which is convenient for you and your partner.
