The Stanhope Ellery is state of the art design and Technology. A Quilted luxury pocketed spring mattress, the Ellery delivers deep conforming comfort and elimination of surface transfer. As a hybrid mattress, the thoughtful layering of high-density foam support layers affords maximum support and conformability. The addition of 2040 Nano coils takes the Ellery to an entirely new level. This group includes King mattress and (2) Twin XL foundations.
