We moved a year ago to a much smaller home. At my old house I had a separate sewing room, although it was small I could move around with a swivel chair. When we moved I had to use my dining room table. I feel your pain there. My DH finished off our basement for his "Man Cave" in the new house and set up the back of the room as a quiltilng/sewing machine room. Yes I did get a swivel chair for it. It's great and helps avoid getting up and down alot. I don't know what type of flooring you have but I never had any problem with the chair moving unintentionally.
