King size wood platform bed is expensive, sometimes costing more than $ 1,000. You can spend thousands more on a bed frame. Or you can build your own use of inexpensive lumber and a weekend. Although there are many varieties of the bed frame, a simple platform box offers clean lines and a modern look. From this basic framework, you can add extras such as a bookcase headboard, or even the posts to hold a canopy.
Cut the wooden beams into six equal lengths to the height you want for your bed frame. Cut sheets of 80-inch and 76-inch plywood so the width matches the length of the cuts of the wooden beam. Sand one side of each of the two sheets of 80-inch plywood, two sheets of 76-inch plywood and the two sheets 80-by-38. Place a cutting beam on each end of the 76-inch plywood sheets, so that the ends and the outer edge align with the edges of the sheet.
Construct an L-shape by attaching a sheet of 80-inch plywood to a 76-inch sheet of sand. Screw the 80-inch blade into position with two wood screws, as you did with step four. Arrange the two L shapes in a rectangular frame. Insert the sheet of plywood without sand into the frame along the center line. Place the 80-by-38 plywood sheets on top of the frame, side to side.
