We bought this for overflow guests. Most of the reviews are complimentary, and we would be as well if it didn't lose it's inflation overnight. It drops enough to incline the user towards the middle of the bed. If two people, it is far worse. The only alternative is to add air during the night. I wouldn't want to wake up realizing I need to find the control and add air. It would be loud, and would further wake you up.Even fully inflated, I wouldn't confuse this with a real bed. It is a single( for the mattress) bladder and feels like it. Hard or under inflated. I have water floate s wih 6 bladders and they work well, why not that kind of control here?Wouldn't recommend.
