Inspired by projects I’ve seen on LumberJocks… My son needed a bed for grad school. I wanted a platform bed that was easy to assemble and transport – there is no hardware, the rails lock to the posts. I was not sure what the window/door situation was going to be so wanted something that could be placed on any wall in any direction if needed. There’s a good recess for the mattress (about 2.25 inches). The shape of the post (triangle/pentagon) gives visual interest and a ton of stability. Height turned out to be really good, the rails & posts are 15 inches off the ground so with a mattress the bed is about the same as a chair. There is 9 inches of clearance under the rails so an 8 inch high storage bin slides underneath nicely. The stock is 4/4 ash, all boards were milled to 6 inches. The lumber was really straight, nice grain, easy to work with (only need to sand it to 220). The rail is doubled at the top so all rails and posts are flush along the top edges. There is an understated cove detail where the trim and rail pieces meet. The finish is a clear hand-rubbed poly. The platform is 4 sections of plywood (27×38) for the base. The posts are permanently joined to the footboard and headboard (those rails/posts are glued and screwed – screws can be hidden). The side rails slide into the posts and lock in place with no fasteners/tools. Aluminum angle iron supports the cross braces (2×4’s – ripped to 3 inches high) are held in place with spacer blocks. The side rails have a triangular peg (screwed and doweled) which fits in the gap in the post and locks the side rail to the footboard/headboard. The side rail exterior trim fits flush with the outside of the post and gives a finished look when assembled. The inside of the post is 8x lumber, cut to fit, and gives the post a nice, unique shape (the excess from cutting the angle in the 8x becomes the peg). This style eliminates the need for a boxspring so moving in the future is easy.
