Space-saving metal bunk bed frame stacks two sleeping levels in a vertical structure so teens and adults can share a room while preserving floor space. Heavy-duty metal slats on both beds provide stable mattress support without a box spring, and the 12.5-in clearance under the lower bed offers open storage space. Full-length guardrails with a 14.5-in height on the upper bed help prevent falls, while the 3-step integrated ladder provides straightforward access. The upper bed supports up to 440 lbs and the lower bed supports up to 660 lbs.
