A few months ago I purchased used Steelcase Leap v2[0] and am happy with it. It offers lots of customization and my back never hurts me after a long day. I wouldn't be happy if I had to pay the full price (~$1000?) as I tried some other chairs in the past such as Spinalis[1] and my mind was blown away. I don't know exactly the reason I felt so good on Spinalis as it was several years ago. But I do know it was "different" than any other chair I tried (haven't tried many). Hope it helps.
