The chair mat is in place and functioning as it should on an area rug. It does not move around during use. I can't speak to durability yet since I've only had it in use for about 10 days. It seems well made and it is definitely crystal clear. Hope it stays that way.
I bought this chair pad to stop my office chair from destroying my carpet. It is so thin that my chair continues to indent the carpet. Even worse the chair rollers get stuck in the indentations and I can’t move my chair without getting up first. It should clearly state it is not for carpet.
