Six sturdy legs plus four extra supports spread the pressure across this 14-inch full-size platform, which is built entirely from rubberwood and poplar. Fourteen slats extend the life of a mattress by supporting it evenly, and no box spring is required. The 10.5-inch storage space underneath handles bins and suitcases. Two adults can sleep on it comfortably without sagging, with a 500-pound capacity. Product size is 74.5 by 53.5 by 14 inches for a 54 by 75 inch mattress; 61.5 pounds.
