You get the best of both worlds—the pressure relief of cooling gel-infused memory foam, coupled with body contouring pocketed coils for superior support. Rest assured that high density quilt foam provides the comforting feel you love. Plus, this mattress arrives in a box for quick easy setup. Simply bring it to your room, cut away the plastic wrap, and unroll. Foundation/box spring available, sold separately.
