The air has stayed in for 1month so far
Great little air cushion  and the air has stayed in it  But a little small ,though I bought it for my car to sit on for long trips ,I am a small person 5' 120 lbs  My car is a mid size nissen  so I would have bought a size bigger.  But I do use it as a pillow sometimes and put it behind my back when I'm sitting
