The Leggett and Platt 733G bed frame is designed as the ultimate bed support for a standard Twin size or Twin extra-long mattress. It features 4 recessed legs on each corner for safety with cross arms for stable mattress support. It features Wedge-Lock construction for simple assembly which promotes strength and durability. The bed frame becomes stronger as more weight is applied. The polyurethane poly-glide legs are best used on hardwood and tile floors so that they will stay in place and prevent bed movement. Frame will adapt to 10 inch height. Headboard bracket included. This bed frame must be used with a box spring foundation.
