Low Profile Twin Foundation — 5-Inch Metal Base in a Box Dining Benches 75-inch gel memory foam lumbarFive inches instead of nine: this twin foundation gives a mattress the rigid support of a box spring at nearly half the height the right call for kids' beds, bunk adjacent low frames, and anyone who finds modern mattress stacks towering. Steel construction, not springs, so there's nothing inside to wear out. It ships flat in one compact box, assembles with the included tools, and wears a removable fabric cover with rounded corners for shin safety.
