The question is always: what do you expect? What one would like to achieve or have? I wanted a makeshift bed, if I maybe 4-5 times a year on weekends Stay elsewhere. There is also sufficient. It loses in just one night air, then is pumped to halt. However, there is an extreme shortcoming! If you lie on the mattress almost everything is ok. One hears then as the air somewhere bulging plastic again. If you have, for example, slept a whole night on the bed (yes, a whole) and then gets up) the next day, then it makes that noise too .... and that for a whole hour! This not only interferes with other people in the room during the night but in the morning when it there constantly making noises that I can not really describe, although no one is sure.
Conclusion: It is an emergency solution, if one wants to get rid of these stupid folding beds, where you also the same could sleep on the floor and would achieve the same effect. It will be enough for my few times, but you should dig deeper into their pocket, if you really want to let guests sleep on. I would be just too embarrassing.
