This is a Coleman inflatable mat, double size. Used only a few times, the mat has no noticeable stains. There are no air leaks. The bag has slight scuffs (photo 9). A down repair sheet has been applied to the back to prevent the hole from widening. There are no problems when inflating. The strap to secure the mat when rolled up is missing one of the two originally included, but there are no particular problems with storage. I personally didn't find it difficult to store. (If you are concerned, you can probably find a simple black one at a home center for a few hundred yen.) Price is not negotiable. Size: 198 x 132 x 9.7 cm Features: Compact Brand: Coleman Color: Black Product Dimensions: 2 length x 1.28 width x 0.1 thickness m Material: Polyester [Usage scenarios] It can be used for camping, outdoor activities, car camping, guest use, and disaster preparedness. [10cm thick cushion] The 10cm thick polyurethane foam is not easily affected by uneven ground, and it distributes body pressure to support the body, allowing you to sleep comfortably like a futon or bed. Also, it is difficult for cold air from the ground to pass through, so you can sleep safely even during cold weather camping. [Self-inflating mat] When in use, opening the valve fully will automatically suck in air and inflate. [Adjustment] If you feel that the inflation is insufficient, you can use the included storage case as a pump to add air. [Storage] When storing, by placing the yellow check valve outward, you can prevent backflow when expelling air and fold it up firmly. [Pump] By using a separately sold mobile pump, you can inflate and deflate the mat more easily. #AirMat #AirMat
