Amazing Ana White Couches

I did add slats to the back as well as the sides as you can see in the photos. This was to hold the cushions in place and make sure they didn't fall out. Worked out very well. The 5 additional verticle slats were 11 1/4 inches and required no further purchase as they were made from the scraps. I also added the additional horizontal slat on the sides using 5/8 decking board left over from building the deck. The sides measured 25 1/2 to fit inside the arm and was 1 1/2 inches from the inside of the couch. I simply screwd them in from the front and back. The rear horizontal piece measures 75 inches and create additional support for the back cushoins, which in this case I used 17x17 inch pillows. I simply screwed this piece into the rear verticle slats. I finished all of it off with a 1/16 roundover bit with my router to make "soft" edges. All-in-all I think that the small changes made for a very polished looking and stout piece of outdoor furniture!
