Behold the newest foundation of comfort. This 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 and without using any tools, creates 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.
