I used to sew on a floor with no carpet, and the chair moved TOO much. When I would push back to get up, it would go flying. Even when I was just sewimg, sometimes the angle of my feet would push the chair back from the table. I was constantly chasing the foot pedal around. As much as I don't like pins getting caught in the carpet, on the uncarpeted floor, they would easily get whisked to another place on the floor, which made them much harder to find. So my input is - I would rather sew on a low pile carpet than no carpet.
