The mattress is very stable, has a spacious sunbathing area. Looking for a mattress folding solution I've seen tons of mattresses, which were unfortunately only half as thick and consist of white foam. As soon as one lies down on it, you feel the ground. This mattress is the only that I could find throughout the Internet, which is 15 cm thick and provides a pretty good guest comfort. When I unpacked them, I was skeptical at first, because she arrived vacuum packed. After about an hour at room temperature have unpacked the mattresses (I bought two) almost reached its full size and strength. The description is that one should leave a maximum of 2-3 days are open, so that they fully unfold again. I've already sample located and find it really great. 4 cm Viskoseschicht fit while lying perfectly to the body and be able to. I feel really comfortable on it. And ultimately is simply second to none compared to the simple folding mattresses price. Quite amazing ...
