Couch or bed uses standard lumber, a standard mattress.

Literally a sofa bed, this bed-seat has a standard 39- by 75-inch mattress as its bottom cushion. Large bolster pillows transform it into a comfortable couch. Standard lumber is used throughout, with lap or notch joints formed with dado blades on a radial-arm or table saw.

You'll need two 10-foot 12-by-3s, three 8-foot 1-by-4s, two 8-foot 1-by-3s, three 8-foot 1-by-1s, a 40-by 76-inch piece of 5/8-inch plwood, 3 feet of 3/7-inch doweling, about 100 1-1/4-inch #8 woodscrews (and matching screw pilot), wood glue, sandpaper, and polyurethane finish.

To make the mattress frame, cut pairs of 1-by-4s to 40 and 77-1/2 inches. For dowel plugs, drill pairs of 3/4-inch holes 1/4 inch deep into the sides of the long 1-by-4s, at each end, then use a screw pilot to drill screw holes through these holes into the ends of the 40-inch boards. Glue, set pairs of screws at each joint, and glue in short lengths of 3/4-inch dowel to plug holes.

Glue and screw a 1-by-1 strip 1/2 inch above the bottom edge of the assembled fram (see top right circled detail). Also use screws to attach plywood to this lip.

For the two end frames, cut two pairs of 2-by-3s to 22 inches and two pairs to 36 inches. Cut 3/4- by 2-1/2-inch half-lap tongues on al ends; make sure they're on the same side of each board.

On the 22-inch boards, also cut a 3/4- by 3-1/2-inch notch on the long (tongue) sides, starting 7 inches above the floor.

Select two boards as back uprights. Face them tongue-to-tongue (middle notches face each other). Cut 3/4- by 2-1/2-inch notches on their back edges to hold the back slats: the top notch starts at the top of the 2-by-3, the other 5-1/2 inches lower.

Now cut 3/4 inch off the back tongue of each 36-inch upper arm. Assemble the two end frames, predrilling pairs of 3/4-inch holes 1/8 inch deep into the 22-inch boards, then gluing, screwing, and plugging the holes as before. (They will be on the inside faces of each frame.)

Fit end frames onto mattress frame, with back edges flush. Predrill 3/4-inch holes for dowel plugs 1/8 inch deep into end frames as in the diagram, then use a screw pilot to drill holes into mattress frame. Glue, set screws, and plug holes with dowels.

Finally, cut the two 1-by-3 backrest slats to fit, and attach with screws and dowels. Sand all dowels flush, sand all edges round, and finish with polyurethane.
