Modern Outdoor Chair Mod with High Back and Full Couch

I made a few modifications to the Modern Outdoor Chair build, including adding a larger backrest and making a couch version that can fit 3-4 people. I felt the original plan didn't hold up the couch cushions well unless it was against a wall, so the modification solves this simple problem!

Wood was Douglas Fir for the price point, although I would've preferred a harder wood. The stain was Minwax Wood Finish in Gunstock 231, Which I felt really sold the Doug Fir as a darker, more elegant wood.

Cushions were from Target and were the cheapest I could find. They've already started to flatten a bit but I plan on restuffing them soon.

Sketchup file available if you need it, but didn't see a way to upload it directly.
