The EveryRoom Bloor Twin over Twin Metal Bunk Bed is a small space dream come true. Built to stand closer to the floor than the average bunk bed, it also features a strong metal frame, full length top bunk guardrails and an integrated secured ladder to ensure your child’s complete safety. Designed to maximize space, your little one will have more room to study and play. The Bloor fits two standard twin size mattresses (sold separately) with a maximum top bunk mattress thickness of six inches. Thanks to the secured metal slats, no additional box spring or foundation is required.
