This is a mat for two people. It's quite comfortable to sleep on. I've only used it twice for camping, and have stored it rolled up since then. While there are no noticeable stains or scratches, there may be minor dirt or dust from use in a tent, as well as dust that may accumulate during storage. There are also initial creases and folds, but please purchase only if you understand this.
