Twin metal daybed with trundle combines everyday seating with an extra sleeping surface for guests in living rooms, bedrooms, or guest rooms. The powder-coated metal frame with slats and sturdy support legs distributes weight evenly, allowing the sofa bed to support up to 550 lbs. The matching trundle bed supports up to 265 lbs and slides out smoothly on four flexible casters. Lockable wheels let you kick down the brakes to keep the trundle in place, and both frames fit twin mattresses without a box spring.
