I used this once for camping, and it was comfortable to sleep on. However, it takes up too much space in the car, so I haven't used it since. I'm selling it because I don't plan to use it again. It's black. Please refer to photos 6 and 7 for the size and weight. As shown in photo 6, the bag is about to burst and is slightly frayed. Please understand that this is a used item. It has been stored at home, and I have inspected it myself, so please refrain from purchasing if you are overly concerned about minor details. It will be shipped in simple packaging. Type: Air mattress Features: Double size (for two people) Thickness: 5-8cm
