A dual-use steel bed frame/foundation is a complete support system that replaces the need for the traditional box spring and bed frame. It is constructed with 100% steel to provide maximum support and durability for long-lasting use. You will find that its 12 points of contact from the mattress to the floor add strength, stability, and level of support. And, their innovative design allows the dual-use steel bed frame/foundation to be folded for portability. Another feature is the 17 inches of under-bed storage to keep those needed items conveniently stored away.
