Purchased two months ago and used once. There are no noticeable scratches or stains. This is an all-around model that combines durability and versatility. The newly developed 3D body mapping baffle, which curves gently, provides a sense of stability that feels like you're being enveloped, unlike a typical air mattress. You can enjoy the comfort of a lounge chair even on uneven terrain. The included Vortex pump sack makes it easy and quick to inflate, and when storing, you can deflate it all at once by simply opening the deflation valve.
