I just removed the carpet in all common areas of my home and my sewing room and replaced with hardwood. LOVE LOVE LOVE it. No more threads or pin/needle worries. So much less dust in the room. My chair is a joy to roll across the floor now. Everything said above is true. My foot pedal seems to stay in place better now. I used to have to chase it across the floor all the time regardless of what I put on the bottom to keep it still. I am going to get a small oval braided rug to put on the floor in front of my TV - just to muffle a little of the hollow sound in the room and so my babies (two dogs) can lay on it while they hang out with me. After 6 months, I would not go back to carpet in there. Ever. It always seems so much cleaner (even when not clean) and it is so much easier to clean.
