The Alton Twin Over Twin Metal Bunk Bed combines timeless style with heavy-duty durability, making it perfect for kids, teens, or adults in bedrooms, dorms, rentals, or institutions. Its sleek matte square metal frame and space-saving design are ideal for small rooms, with 10.6 inches of clearance underneath for convenient storage. Built to last, the sturdy square tube frame supports up to 350 lbs on the top bunk and 400 lbs on the bottom. Safety is a top priority, featuring full-length guardrails and a secure, wide-step ladder that can be installed on either side. Noise-free metal slats, firmly fixed with plastic buckles, provide a quiet and immersive sleep experience. With no box spring needed, the strong metal slats offer excellent mattress support and help prevent sagging. Assembly is quick and easy—two people can set it up in about an hour. Designed to fit standard twin mattresses, it’s recommended to use a 4"–6" thick mattress for optimal safety and comfort.
