Enjoy endless possibilities for restful sleep with this hybrid innerspring California king mattress. You get the best of both worlds: the pressure relief of cooling gel-infused memory foam, coupled with body-contouring wrapped 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.
