This floor bed has no slats: the mattress sits directly on the floor inside a 78 x 42 x 16 inch pine fence, with 12 inch guardrails on all sides and a 16.5 x 12 inch gate that latches shut and can be mounted on the left or right. Above it rises a house-shaped headboard to 74 inches, a pitched roof frame meant to be dressed with curtains, light strips or flags (decorations not included). A clothes hanger rail fits on the side of the bed or fixes to the wall for tomorrow's outfit. Overall footprint is 78 x 48.5 x 74 inches and it takes a standard twin mattress up to 6 inches thick. Solid pine wood in a natural finish, 44 lbs net weight, assembly required. Without a frame to climb, toddlers moving out of a crib can get in and out by themselves, and the fenced floor doubles as a play corner.
