I built 2 of the 2x4 couches with slight modifications. I didn’t like the straight bar across the back so changed it to a leaning high back.
I also added a square box that can be used for a dividing table on the couch or side table when additional seating is needed.
Plan on scaling down for a love-seat and chair.
Kreg jig for pocket holes was time consuming but well worth it!
Not pleased with the urathane finish after 2 years. I have begun sanding them down to try a linseed oil finish instead.
