Build Seat Frame:

To make the seat part of this sofa, we are basically going to frame up a mini floor. Just attach 5 of the 25-1/2” long 2x4s to 2 of the 72” long 2x4s, spacing about 16” apart. Use 2-1/2” exterior decking screws. This completes the seat frame.

Arm Tie-In:

To finish the arms, add another 25-½” long board underneath the arm middle. We’ll use this board to tie into the seat framing in the next step.
