This 10-inch king pillow top innerspring mattress and foundation set combines top comfort and endless possibilities for restful sleep. You'll love the inviting feel of the mattress’ soft top surface with high-density quilt foam. The firming pad and high-density body foam work with each of the pocketed coils of the coil unit to contour to your body, for a traditional feel that delivers pressure point relief and the firmness you need. A layer of high-density gel memory foam is built into the mattress to provide restorative support for your lower back. 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.
