Full size Montessori floor bed creates a low-to-ground sleeping or play area so children can climb in and out independently. The solid pine wood and plywood frame forms full-length safety guardrails around the 77 x 57 x 16 in structure to help keep kids on the bed surface. A 75 x 54 in sleeping area fits a compatible full size mattress up to 8 in thick. The entrance opening measures 19 x 12.5 in, and the lockable door with latch can be used closed, open, or removed for flexible access. Smooth, splinter-free surfaces support everyday use.
