I made the "Outdoor Loveseat" from the "Modern Comfort Collection". The plans were very helpful! As a true novice, one issue I ran into was that the seat back bottom slats was about 3/8" longer than would fit. In any case, I was able to trim the boards down and the seat looks great. I ordered the cushions from Amazon.
The seat is now at my father's house where he can sit in the sun - when it's warm enough (in the spring/fall/winter) or cool enough in the summer. The build time was longer because I cut the wood and pre-assembled major pieces at home and then drove the pieces to my father who lives out of state.
Thank you for sharing the plans!
