This firm queen mattress and foundation set is just the right combination for perfect sleep. Enjoy restful nights and refreshed mornings on a mattress that doesn't “give” too much yet still pampers with cradling comfort. Ideal for back and stomach sleepers, this mattress has five levels of high-density foam (including a layer of gel memory foam for temperature regulation) to provide the ideal balance of comfort and support. Rest assured, 720 power packed 15-gauge wrapped steel coils offer reinforced structural support where you need it most, while 13-gauge wrapped coils provide edge support so you can stretch out comfortably and enjoy a more supportive sitting surface. The foundation is an all-in-one support system that takes the place of an ordinary bed frame and box spring. The metal unit sets up quickly, without using any tools, to create a sleep haven with unwavering support. The clearance from frame to floor is spacious enough for under bed storage. Included brackets attach the riser to a headboard.
