I purchased this new and used it for two seasons, about five times in total. When used, I always laid a mat down and slept on a sleeping bag on top of it, so I never slept directly on it. I am selling it because the size no longer fits my needs due to a change in tents. *Mat only, air pump not included.* I used it with my child and family of three, but there was space for about two more people! There are no noticeable stains, but since I used it for camping, there may be some scratches and slight dirt from use. I would appreciate it if you could understand this point. I couldn't fully set it up inside my house. I have uploaded some photos of it, so please take a look. I have the original box, but the shipping label was attached directly to the box when I purchased it online, so there are sticker marks. I plan to ship it in this box.
