Hi! While attending a machine-quilting class, I fell in love with the sewing chair I used there. I just ordered a #258 Dynamic Series, with adjustable Lumbar Support. It moves up/down and the back rest is movable also. You can choose your fabric. It has no arms. I opted for the wider seat (22", I believe). I am 67 and have back problems and lots of arthritis everywhere. I can't wait for this chair to arrive. The order form states: Ergonomic Advantage, Omaha, NE. Website:
