2x4 and 2x6 Chairs and Couch

I used the Modern Outdoor Chair from 2x4s and 2x6s plans and slightly modified then to make a 3 seater couch. My cushions(most expensive part) were 24 in x 24 in and purchased from Lowes for $40 per seat. The couch is 79 inches in total length. I also dropped the seat down to the lower level to allow more room for my cushion backs to sit further down into the seat.
