Title: doesn't stay fully inflated
Review: Mattress loses some air during the night and although you can still sleep on it, it goes from firm to soft. It was that way when it arrived but it seemed too much trouble to exchange it by mail. We still use it, but it probably would've been a better idea to buy it at a store nearby and be able to exchange it easily.
