Thank you for looking. This is a Coleman air mattress (double size) purchased about 9 years ago. It is recommended for everyday use, camping, and car camping ♪ ① There is one clear defect! As shown in photos 1-3, when inflated, one of the four corners inflates abnormally. I suspect that the seams connecting the 40 circular indentations on the mattress to the back of the mat have separated because the seller overinflated it (fortunately, it is not punctured). There is enough sleeping space for one person, but the abnormal inflation may get in the way for two people. ② I have lost the original box, and I don't recall there being an instruction manual. The instructions written on the side of the product are sufficient for packing it away. ③ The fabric on the underside of the mattress has a texture that easily collects dust. I have cleaned it with a vacuum cleaner nozzle, but there are limits to how much dust can be removed. Since this side faces the floor, I believe it will not be a problem for use. Other than these points, there are no stains, scratches, or tears. Please consider purchasing after understanding these three points. - The original inflated size is 189cm x 138cm x 19cm thick. - The product has been cleaned with a vacuum cleaner and alcohol wipes. - For shipping, the product will be placed in a plastic bag and packed in a box with appropriate cushioning (newspaper, etc.).
