Functionality and beauty come together to make every little girl’s dreams come true with the Double/Full Bookcase Bed. For extra storage space and organization, pair this with our Underbed Storage Unit or our Trundle Unit, both sold separately. This bed features a hi-lo adjustable locking system that allows beds to work safely with or without a box spring. The Hi-lock position raises the bed to accommodate under bed storage or sleep options. Comes complete with wood slat roll mattress supports; no need for box springs or "bunkie boards". Carefully chosen hardwood solids and veneers provide long-lasting durability.
