I ordered this mattress because of the many positive reviews for me and my wife (85 and 60kg). We were only really happy with it, because she was really super comfortable and made a very sophisticated look. After about half a year began with my, as well as the copy of my wife, to form a hollow, even though we used every 4 weeks. This was formed from more and more, so that we now, after just two years, have the impression to sleep in a hammock! This manifests itself in very poor sleep and back pain after waking up. If it would have affected only one of our mattresses, you would still be able to explain it with strange sleeping habits. But as I have come to the conclusion that the quality is not nearly in accordance with the price. I am very disappointed not only of this mattress, but also by Stiftung Warentest, the "good" tested this mattress.
