I have carpet too, and don't like it. My chair is hard to roll and pins and needles get lost in it. My DH is usually the on who finds lost pins by stepping on them. Serves him right since he doesn't wear his slippers. He thinks I drop them on purpose. I would love tile, but I'm afraid it would be too cold. Hard wood is my second choice. Probably won't have either, since the carpet is only 5 years old.
