The RealRooms Burleigh Full over Full Bunk Bed Frame breaks norms with its open, clean-cut, and industrial-modern style. Our heavy-duty metal full-size bunk bed for adults, teens, and kids features a powder-coated steel frame, resisting rust and corrosion, for robust use in your kid's room, vacation home rental, or guest bedroom. Providing enhanced safety, this kids' bunk bed includes 12" full-length guardrails on all top bunk sides and a reinforced ladder. Rotating the space-saving frame allows for ladder placement on either side, presenting flexible layout options. The spacious 46.5" gap between the bunks offers welcome breathing room, and the 10.5" bottom bunk under-bed clearance delivers storage space. Superior to other bunk beds on the market, clip-in slats and the included ratchet tool speed up and simplify setup, while the noise-reduction technology minimizes squeaks and creaks. Fitting two 6" full-size mattresses without box springs (sold separately), the upper bunk holds up to 300 lbs. (recommended for individuals 6 years old and up) and the lower bunk supports up to 350 lbs. (for persons 3 years old and up).
