I bought a kneeling chair during the pandemic. I've used and enjoyed them in the past, so I already knew what I was getting into. They are pretty hard to adjust to, and IMO one ought not stay on one for several hours at a time, but after several months of using it I feel like my posture is dramatically improved from my past slouchiness.
