Twin Over Full Bunk Beds with Stairs Design

Twin Over Full Bunk Beds with Stairs Design.

The rails are attached in the same way, placing a set of rails 7 3/4 inches above the upper bed frame and the other set 4 3/4 inches from the first set of rails. You can give the beds more support by cutting two and four pieces into pieces that will fill the spaces between the frames and rails and then nail them to the inside of the corner posts. You can also attach steel bar hook brackets to the top of the stair using thumb-long hexagonal screws.
