I've got one of those ALITE Monarch 2-leg chairs available, if interested. It's very comfortable, allows you to stretch your legs out straight, and acts somewhat like a rocker since it pivots on 2 legs. Excellent, like new condition.
It's a little tricky getting in and out of at first, but once you get the hang of it you'll love it. The first photo is the best I could show of its shape. The second photo shows it's packed size next to a size 9 flip flop.
