Utilize your under-bed storage with the adjustable bed risers by Structures™. With three different heights options, 3", 5" or by stacking both to achieve 8", the risers create up to 29 cubic feet of storage space. Made of reinforced high-impact plastic, the heavy-duty risers can hold up to 2000 pounds. The risers also ensure safety with a recessed top that can hold a bed frame foot up to 2 3/4" wide. In addition, the bottom of the risers are padded to prevent damage to floors and its shape avoids harm to carpet.
