Memory foam mattresses are a hot trend for good reason, but for some they simply get a bit too toasty for comfort. Rest easy. This 12-inch king memory foam mattress and foundation set has you covered with the cradling feel you love and temperature regulation you crave. Soothing memory foam contours to your body, while a thick layer of firm support foam provides wonderful pressure point relief. And how's this for cool: Thanks to dual ventilation technology, you get a more breathable memory foam mattress. It's topped with a micro cool technology cover to keep you that much more comfortable. The mattress riser 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. Included brackets attach the riser to a headboard. Even better: The clearance from frame to floor is incredibly spacious and ideal for under bed storage.
