I also am unable to stand for more than about 20 minutes. I have a mini and a midi side by side on low stands. I use an old office chair,arms and back removed but wheels still on. I have everything for the pen turning/finishing process within reach (that is within ROLLING reach). The variable height function of the chair is beneficial, and I find there is plenty of stability even with the wheels. I do not think this would work as well for larger turnings. I have not stood at either lathe EVER, and have been turning pens for about four years. I think some who now stand at their pen turning might decide to switch to the seated mode if they ever tried it. I wish you well...NOW, SIT DOWN!
