For the headboard, build the outside frame using 1 1/2" pocket hole setting and 2 1/2" pocket hole screws. 2 screws are recommended per joint. Glue is also recommended.

Next, add the center piece. We choose to inset this one a tiny bit just for interest, but it's really up to you here. You'll need to attach here with 3/4" pocket hole setting and 1 1/4" pocket holes.

Add the remaining two pieces to make up the decorative pieces in the headboard.

Drill 1/2" pocket holes (set for 1/2" thick stock) around the sides of the 1/2" plywood. Then attach with 1" pocket hole screws from back side. Also use 1" nails to attach to center boards with glue.

Now connect the headboards and footboards together with the 2x4 inner side rails. Bolts, 3" screws or bed brackets here. You could also use pocket hole, but remember, these are the main joints that hold the weight of the bed, so you want to make sure this joint is strong.

Also, if you have a box spring, you can adjust the width to accommodate the box spring exactly. Just remember that the box spring sits on top of the bed rails.

Attach decorative side rails to the inner side rail. You can also attach these to headboard and footboard for added strength.

Check with your mattress on slat recommendations. When in doubt, add more slats than needed. For heavier loads, 2x4s could be used. Attach slats to the inner side rails.
