Solid wood, plywood and MDF with plywood slats help support up to 240 lbs on the upper bed and 240 lbs on the lower bed. The frame measures 78.5 x 43.5 x 65.5 in and includes an integrated ladder with a wide entrance for easier climbing. Full-length 14-in guardrails on the upper bunk help keep kids contained while they sleep. An 11-in under-bed space leaves room for storage and cleaning access.
