I picked up the lightest REI chair (1 lb 1 oz in the stuff sack) last summer, but have only tested it out on day hikes so far. It's pretty good in terms of comfort, though a bit tippy and will sink in soft ground. At least now I have the option for backpacks. I expect I'll wait to inaugurate it on a trip where I create a base camp rather than one where I cover ground every day. As I continue to age I think I'll start doing base camp trips more often.
