The Big Agnes chair copy looks interesting. I think I'm going to make a copy of the Crazy Creek chair out of 1.1 Ripstop with some carbon fiber stays. I'll use some blue closed cell foam for a bottom. Hopefully it will work. It should be a lot lighter.
Hammocks work great at camp, but I need it to be more mobile. I'm an animal voyeur. I like to watch deer, elk, etc. with binocs and a spotting scope. Sitting and glassing gets hard on my back after a little while. A chair makes it a lot more fun.
