Ah, Steve, I am very familiar with Adirondak chairs. That was one of my student's favorite projects when I was still teaching. A few years ago I pirated some plans of two different styles of chairs off the internet, combined the features I liked from both, made a set of patterns, and we made dozens of them. Since I retired I have been making a few chairs and selling them to friends and neighbors. People comment on how comfortable they are, even after sitting in them for extended periods. I believe it is because of the contoured bottoms. These Kirkey seats are similarly shaped in the bottom, so I should be able to get by with very little padding in the upholstery.
