Title: 2 and 1/2: sometimes good, sometimes bad Review: I bought two of these during the holidays last year, and have since used them 3 times for adults, no kids have been near them. They were on super sale and I think we got both for twenty bucks and planned to stack them for extra comfort. The first time, they were ok, they did need extra air added every day, but they stayed inflated. The same went for the 2nd time they were used.The third time didn't go so well. One of the mattresses completely deflated(with no one on it) within 2 hours. For the price, I'm not really mad, but I was disappointed. They are comfortable, but they require maintenance to keep them properly inflated during use, which is a pain in the neck. If I had to buy air mattresses again, I probably would avoid this brand.
