While futons have a bad reputation for being uncomfortable to sleep on, they make up for that in their ease of use and flexibility. Having a futon in your home means that you always have a spare bed, and it's suitable for studio apartments that need to have a sofa and bed in one. However, one of the aspects of futons that take some getting used to is the fact that they don't have headboards. But you don't have to get used to it; you can easily make your own headboard that's as versatile and flexible as your futon.
Put on rubber gloves and moisten a soft cloth with acetone and wipe down the pipes. Measure the 40-inch length on each pipe and mark it with a pencil. Cut the pipes at this mark using a PVC cutter.
Cut a piece of fabric that is 40 inches long and 45 inches wide. Wrap one end of the 40-inch long side of the fabric tightly around a PVC pipe. Pin it in place. Wrap the other end of the fabric tautly around the other PVC pipe. Pin it in place.
Sew the wraps you've made in place with a sewing machine, using a running stitch. Slide the pins out of the fabric.
Drill a small hole through the fabric and the PVC, an inch from the top of each pipe. Measure the distance between the two holes. Hammer two nails into the wall 40 inches high and the width of the measurement you just took.
Press the holes into each nail to hang your convertible headboard against the wall. Press the lowered futon against the bottom of it to help hold it in place. Remove it from the wall when your futon is upright, and roll it up.
