No chair is precisely right for you unless it’s made for your body.
Build chairs made to measure from exclusive materials, and that conforms to your body and working habits.
It’s more than likely that whatever chair you choose you’re making some kind of compromise. It was not designed specifically for you.
Build a sensing and inflating mechanisms into the chair. The sensors will sense when some of your muscles are beginning to lax and would cause the right element to inflate in order to compensate for that.
