Slip a low-profile mattress support under any full-size bed in minutes with this 0.4-inch foldable bunkie board made from eight pre-connected pine plywood slats. Nylon webbing joins the pieces together so the entire board unfolds flat for support and folds compactly for transport or seasonal storage. The Burlywood finish complements both metal and platform bed frames, and ready-to-use construction skips assembly entirely, making it a quick fix for sagging mattresses, sleeper sofas, and bunk beds across guest rooms and dorm setups.
