Steelcase Gesture. I am 310 lbs, 5'10". I bought one at the start of the epidemic when it was on sale, new for ~$1k (directly from Steelcase). After a recent change in work plans (going full time WFH post COVID), I decided to get a second, but the price had increased to ~$2k for the same configuration. Was able to get a factory return in pretty much the same configuration and like new condition from a US based liquidator, Crandall Office Furniture, for $780 shipped. (They do authorized Steelcase factory returns).

I like this chair over Aeron as I don't like floating mesh seats. It's fabric so it breaths. Has good options for me to change it's configuration quickly/easily through out the day.
