LIke most air beds, it's a bit of luck that they don't lose some or lots of air. I have a single version of this which doesn't leak hardly at all but a double went down within a few hours of putting it up after a few uses. Decent price. I personally would get one without the pump. I've had this one https://www.amazon.co.uk/Relags-Coleman-Durable-Inflatable-Mattress/dp/B01MZI4ZAO/ref=sr_1_3?keywords=coleman+airbed&qid=1553618235&s=gateway&sr=8-3&th=1 for a few years and has never let me down. Also much smaller for storage. Hot nevertheless at this price!
Great price OP (y)
we bought one of these for camping not realizing they dont have the small valve to inflate using a foot pump or 12v pump which our previous one had. so now purchased a inverter to use the built in pump. I always found our old one kept loosing air & needed inflating due to air escaping from the valve. but this one once inflated stays like it for the whole duration
