I used this three times after purchasing it new. I used it on a sheet, so there are no stains, odors, or stickiness. After use, I dried it in the sun. It inflates with a pump bag, not by foot. It can be used in about 5 minutes. I no longer go camping, so I don't need it anymore.

Open the bag and take in air, then roll it up 4 or 5 times to push the air in, and it inflates completely in 1 minute. Deflating the air is incredibly fast, taking only 1 second! Anyone, from children to women, can easily use this outdoor mat. The tent mat also has a built-in pillow with a separate air inlet, so you can adjust the height of the pillow and the thickness of the main body to your liking. [Thick, Lightweight, and Compact Air Mat] The thick design, approximately 7cm, and ergonomic design provide a comfortable sleep experience, evenly distributing body pressure and preventing sinking, supporting your entire weight in any position for comfortable sleep. It maintains comfort while being incredibly lightweight! The air mat, measuring 190cm in length and 60cm in width, packs down to a compact size of only 27 x 8cm and weighs about 665g. You can easily store it in a pocket or the gap in your backpack. Why not reconsider your backpacking camping gear?
