I bought the chair used on eBay last year for over $250. They are currently selling for anywhere from $200-$350, with new chairs going for over $600. My chair seat is 16" wide and 16" deep. As a small (5"0, 90 lbs) person, I could not reach over the arms of larger chairs well enough to turn the wheels. I had no problems propelling myself in the desired direction with this chair. I hope another "shorty" like me can use it.
