Modway Articulate is what we have for everyone in our office: https://www.amazon.com/Modway-Articulate-Ergonomic-Office-Ch...

At $150 I find it comfortable enough to sit in all day without issue, which is rare even among more expensive chairs I’ve tried. One of our employees has ergonomic issues and loves it. I really like having the ability to adjust seat tilt and back tilt separately, as well as initial back height. The only downside is the armrests don’t go low enough to fit under your desk easily, so we generally leave the armrests off when building them
