Step by step
Step 1
Drill two 1-1/2" pocket holes on each end of the side boards. Attach to front and back legs with 2-1/2" pocket hole screws and wood glue. Build two legs per sofa. Remember that the pocket hole placement should be on the inside, so you will build the legs in mirror.

Step 2
With pocket holes on inside, attach the horizontal supports to the leg sets with pocket holes (1-1/2" setting, 2-1/2" pocket hole screws and glue).

Step 3
Attach back top support to legs with 2-1/2" screws, predrilling holes if necessary to prevent splitting.

Step 4
Drill two 1-1/2" pocket holes on each end of the slat boards. Attach inside the frame. Also screw the sides of the kids couch to the last slats for added structure.

Step 5

Step 6
Build the arms using 1-1/2" pocket holes and 2-1/2" pocket hole screws and glue. Attach arms to sofas to tie the two sofas together and support the back rests.

Finishing
Sand all surfaces, starting with a medium grit and finishing with fine. Wipe off the dust, fill any holes or gaps with wood filler, and sand smooth once dry. Apply primer if you're painting, then finish with your choice of paint or stain and seal with a durable clear topcoat. For outdoor projects, use exterior-rated primer, paint or stain, and sealer so the piece stands up to the weather.
