A supportive destination for relaxation and rejuvenation. This handcrafted mattress creates more surface area with its edge-spring Marshall unit system. Unlike traditional innerspring systems, our heat-tempered center and quantum edge springs are individually wrapped pocketed coils, which result in a mattress that is more responsive to movement with edge-to-edge support. Rest easy with less side-to-side transfer of motion, this collection fits to the contours of the body. A final comfort layer has been redesigned to provide support, comfort and cooling.
