We got fancy ergonomic chairs when moving offices a few years ago and immediately after the move I developed back pain. I tried adjusting the chair and we even had trained professionals come to help us adjust them, but it didn't seem to work. A coworker of mine had gotten a kneeling chair for his back issues at the same office, but that didn't work for him, so he let me borrow it. I noticed a positive difference immediately. The chair is a Varier Wing Balans and I have been using it at work for several years now.
When we switched to WFH due to the virus, we were unable to take office equipment home aside from necessary hardware which was securely shipped to us. Because of this and because the switch was too sudden for anyone to really be able to prepare their home environments, we got an allowance to buy some home office equipment and many people opted for chairs. The Wing Balans was a bit expensive for me to justify, so instead I got the Varier Variable Balans. Also a kneeling chair, but no adjustable height. Aside from being much cheaper, one thing I love is that it sits on two rocking rails instead of a wheeled base. I am a fidgeter and it lets me rock back and forth as I work. It lets me have just as much flexibility in my sitting position as the Wing Balans at the same time.
The one negative is that it can be quite fiddly to place properly - the Wing Balans single swivel foot does not get in the way of certain table legs as much as these two rails. I also learned that to take full advantage of this chair a height adjustable desk is recommended (which we have at work, but which I do not have at home). For example, if I want to sit on it by putting one or both feet up on the shin rests, my knees hit the underside of my normal-height desk. I've purchased a height-adjustable laptop stand which should be here this week and look forward to using the chair with that setup.
