Enjoy endless possibilities for restful sleep with the Chime twin innerspring mattress and foundation set. Soothing memory foam contours to your body, while a thick layer of firm support foam provides plentiful support and pressure relief of your body’s major pressure points. The included 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 and without using any tools, creating 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.
