For a standard twin (38 by 76 inches), should be the longer side measuring 78 inches, while the shorter side should measure 37 inches. Place the box and let the longer ends overlap the shorter ends. Screw together using 3-inch screws. Cover the box with the heavy plywood. Cut to fit and fix at 2-foot intervals, 1 5/8 inch screws. Sand the rough spots until smooth. Your mattress will be on top of the box. Turn over the box and test how well the mattress fits. Place the posts and draw a line in all four.
