This is a 7-inch queen mattress foundation with a foldable steel frame. The folding design makes it easier to carry through doorways and store than a one-piece box spring, and it assembles without tools. It works under innerspring, memory foam and hybrid mattresses. Against fixed wooden box springs, it trades some rigidity for portability and a lower profile. Owners rate it highly overall, though some mention the steel frame can creak and the fabric cover is thin.
