My wife and I think it's very comfortable. It's a little low, but that's kind of an Adirondack chair thing. One thing I like about it is that the back doesn't lean back quite as much as a standard Adirondack chair.That is a pretty cool chair. Is it comfortable? Post the plans
As for the plans, I got them from this website. He has a YouTube channel and a full build video for the chair.
