Children stay away from this poor quality product. I bought it because the dimensions suited me. I inflated it for the first time at home. I left it overnight. In the morning, it had deflated. I found the leak. It had a small hole next to the valve. I got some glue and adhesive. I fixed it. I tried to inflate it the next day. It didn't leak. A little while later, I decided to go to the mountain. The night before I left, I checked the equipment. It was deflated again. I won't go into detail, the mattress is a waste. I thought maybe I got a defective one. I ordered exactly the same one. Well, the second one was leaking exactly from the same spot. Maybe it needed a stronger fabric, at least next to the valve, which is its weak point. Anyway, it's a given that at some point it will develop a leak. And good luck if it happens in the middle of your vacation. You're screwed.
