The best chair varies person to person. There are some good things to try in this thread, but ultimately trying one for a few minutes in a store is not adequate. Buy from somewhere with a good return policy and support. Years ago I'd tried a Humanscale Freedom. In store it felt great. After a day I was sore. After a week I couldn't sit in it for more than 5 minutes without a fiery pain running up and down my back. Back it went. I ended up with a Steelcase Think with the mesh back (I liked it was lighter and simpler vs the Leap), and have been using it for 12 years. 7 of those were working from home full time. In the end what works for me (good chair, fully adjustable thin keyboard tray, height adjustable monitor) may not be right for you. There are no absolutes in ergo. But the guidelines around monitor height, arm angles and positioning, etc are a place to start. Even with the right chair, take a look at the rest of your setup. Wrist/shoulder pain -- Is your keyboard or mouse position OK? Are you using a wrist rest when you should have none? Shoulder/neck/back pain -- How about your monitor height, do you hunch or lean a lot?
