Folding the lower frame turns a twin bed into a sofa, which makes this bunk useful in a studio or a guest room rather than only a child's bedroom. Powder-coated metal slats and three middle support legs give each bed a 485 lb capacity, among the highest in this range, and anti-tipping hardware secures the frame to the wall. Headroom between the bunks is 47.5", with 9.5" of storage space beneath. Guardrails stand 13". Overall 77" x 41.5" x 71". Assembly required; net weight 105.5 lbs.
