I had the cheaper versions which at Norma, furniture stores and co it. are, already tried a few years - this one is the best !!! It is like a normal good bed. I look after a family member and I sleep on the couch, equipped with this mattress at night you will sleep great, no pain Kreutz :-))) The mattress is a lot heavier than other folding mattresses, but that's not going to make sure of the quality otherwise. The only point as an inspiration for the manufacturers - but that will not lead to the devaluation: It would be nice if follow-up models or additional models this thin (softer pad, which is only on one side, and on the lower side were present - thus obtaining the mattress can alternately use time well. If you do this in this, one gets the softer part just not.
