Love a plush, pillowy feel, but need a higher level of support? Look no further than this plush California king mattress. Five different levels of high-density foam, including plush pressure-relieving foam and gel memory foam for temperature regulation, work in concert to provide the ideal balance of comfort and support. Rest assured, a power packed wrapped coil unit offers reinforced structural support where you need it most, while 13-gauge wrapped coils provide edge support for a larger sleep surface and supportive sitting surface. Foundation/box spring available, sold separately.
