Adding an arch can be simple to do an add that extra touch of fancy to the simple bed. This is a modification of the simple bed plans. Special thanks to one of our readers for sharing their photo.

Take four of boards A and mark out the exact same arch in the panels. In the bed shown, the arch starts 6" in on either end and is 3" tall at the center point. Carefully cut out these arches using a jigsaw. Layout the headboard and footboard panels, as shown below. The below diagram does not show the arches cut out. This diagram shows how the spacers (C) are to be placed between each of the rails (B). Start with only 1 of the arched header boards and a straight header board on the bottom. NAIL ONLY THE SPACERS AND THE OUTERMOST RAILS - DO NOT NAIL THE MIDDLE 4 RAILS. Use 1 1/4" nails.
Now let's add the posts. Predrill 1/2 way through the posts on the outside. Then use long screws (at least 4") to screw into the center panel where it is sandwiched between the header boards. Use two screws for the top header and two screws for the bottom header, for a total of 4 screws per post. Center the post on the panel. There should be a 5/8" space between the outside edge of the post and the header board on both sides.
Add the 2x4 (Board E)to the top of the headboard as shown below. THE ARCHED HEADER 2X4 WILL FIT FLUSH WITH THE TOP OF THE BED. THIS IS NOT SHOWN BELOW. Add the 2x4 (Board G) to the top of the footboard. Board G will overhang the posts by 1/2" on both ends. On the headboard, add Board F to the top of Board E, allowing a 1" overhang on all
