Step 1: Cut the White Beams

Cut down the four 4 by 1-1/4 inch white pine beams to 2-3/4 by 1-1/4 inches using the table saw.

Step 2: Attach the Ledgers

Take the smaller 1-1/4 inch square ledgers cut from the larger piece and glue one side of it. Place it on the face of the 2-3/4 by 1-1/4 inch piece so that it is flush with the edge of the beam. Nail every six inches to attach.

Step 3: Cut the Four Beams

Once all four beams are completed, it is time to cut them down to the appropriate size. First, make measurements for the cut. For this project, two pieces were measured to 74-1/8 inches and the others to 50-1/8 inches. Instead of a straight cut, miter these pieces to 45-degrees. Make sure to make opposite-angle cuts at each end and that the angle goes upwards from the measurement, not down.

Tip: Because the blade is 1/8-inch, remember to cut along the outside of your mark.

Step 4: Nail the Pieces

Once all the pieces are cut and mitered, glue each end and nail them together.

Step 5: Apply a Stain

Apply a nice stain to bring the beauty of the white pine out, and let the frame sit overnight.

Step 6: Cut a Piece of the Plywood

Cut a piece of the 3/4-inch plywood to 72 by 48-inches.

Step 7: Lay the Foam Topper

Lay the plywood down and cover it with a queen-size memory foam top. Fold one side over and spray adhesive over the plywood. Roll the foam topper over the adhesive and press down. Repeat the process for the opposite side. Trim off the excess foam so the mattress top is flush with the plywood.

Step 8: Lay the Fabric

Take the fabric and lay it over the memory foam. Smooth out any wrinkles and staple to the back of the plywood. If the fabric is woven or see-through, lay down a solid piece of fabric before placing the main cover, giving the headboard a more attractive look.

Step 9: Attach the Plywood Section

Once the headboard frame is dry, set the plywood mattress section inside. Attach it by countersinking up through the frame ledger into the back of the plywood.
