Engineered to reinforce the center of the mattress where the heaviest part of your body lies, the exclusive Posturepedic technology provides targeted support to your back and core so your body stays level while you sleep. The exclusive zoned CoreSupport quilt technique uses additional foam in the mattress quilt area, for reinforced support where you need it most for long-lasting comfort. The revolutionary ComfortSense foam is the latest generation of conforming foams that feels like memory foam, is as durable as high density foam and is designed to be more breathable for a more comfortable night's sleep. Sealy's proprietary PROBACK layer provides even more targeted deep-down support to your lower back and hips where 60% of your body weight lies, for extra durability and years of pressure-relieving gel infused memory foam comfort. The zoned conforming pocket coil system has individually encased coils that move independently and are more densely packed in the centre of the mattress to provide more targeted support where you need it. The SolidEdge support is a reinforced foam border around the mattress edge so you can use the full surface of the mattress, as well as providing a solid seating surface. The cool gel infused comfort from the CertiPUR-US approved high density gel infused foam provides long-lasting, flexible, durable support.
