Four functional zones share this twin loft bed, combining a 75 x 38 in sleeping surface, an under-bed study area and an open bookshelf to organize a compact room. The metal frame with 20 metal slats supports a twin mattress up to 6 in thick without a box spring for stable sleep. An 11.5-in high integrated handrail, protective corners and a wide entrance provide contained yet comfortable access. The built-in bookshelf serves as a climbing ladder, so the user can reach the bed and stored items without extra furniture. A rolling study desk with a 38.5 x 16 in tabletop glides out on smooth universal wheels for homework, then tucks away to clear the 60.5 x 33 in under-bed clearance for reading, storage or play.
