I have never used a long arm quilter but it seems to me that you could use a bar stool to sit at it. If it had wheels you could scoot back and forth. My DH has one from Costco in the garage that has a back and is height adjustable and has a place to rest your feet. Don't know if this would work but it's worth thinking about. I agree with other posts that you need to try out whatever you buy because it's a major investment. Maybe get to a quilt show to see and try them out first.
