Decide how best to attach the headboard to your bed frame. For our standard metal frame, we used a piece of 1-by-4-inch pine cut to the length of the bed frame. We spaced the four chairs along it, adjusting the height of the chairs so that plenty of headboard would be visible once the mattress and boxspring were in place. Using a screwdriver and 16 wood screws, we attached the chair backs by their legs to the board. Finally, we bolted the headboard to the metal bed frame.
