Chairs depend SO MUCH on your height and ergonomics.
I am only 5'2' so I had difficulty finding chairs to accommodate my needs. Many chairs can go low enough, but the seats are deeper to accommodate taller people, too, which means that I end up slouching or using a pillow to reach the back of the chair. I was dealing with a LOT of back and shoulder pain as a result.
Once I went to WFH, I tried a couple of different chairs marketed for office or gaming (without success) before a coworker turned me on to the one I have now- and I ADORE IT. I use it for work and take it out to do crafts/ sewing as well. It is like a doctor's rolly chair- no arms, adjustable height, lumbar support. I have an old 4" aerobic step ( just one layer from a garage sale) to prop my feet on when seated. I am happy with the setup and it is comfortable for my needs. I work from home VRS and have a sit to stand desk that I love- so I alternate throughout the day which is also helpful. Hope this helps
I’ve purchased two of these (both times from the open-box discount option) and I don’t think you can get better for the money. No footrest, but I have a folding one as needed.

I got this one: https://smile.amazon.com/gp/product/B0019QF7JI small, no arms (which I didn't want anyway). Adjusts up/down, so was good for my desk and elevated table. It's a bit firm (but not as firm as the bucket)
