The Gästematraze seems to have a good foam core: He is probably thicker than usual, it does not sink in, but it is very stable, but he seems nevertheless well adapt their own bodies. I could at any rate prima sleep on. [Update June 2015: Half can not sleep well on the mattress and the next day very tense. Also I find now that the mattress is quite hard after prolonged lying / regular use. So perhaps rather for someone who prefers hard and soft mattresses.]
The mattress does not stink and appears to be largely processed well. Only the handle loops act measured sewn slightly too thin on the weight of the mattress, which they must keep.
What is important to me also: The cover can be removed and washed.
Criticisms:
[-] The mattress while wearing a Oeko-Tex 100 certificate, but its authenticity / validity could not be confirmed based on the test number of the Oeko-Tex website. And also with the brand name / brand name you could not find in the Oeko-Tex database.
[-] The dimensions are not for Gästematrazen bad and in the usual range, but it is not a standard size, for example, you get Molto pads or clamping covers. You have to buy a bit bigger this so.
[-] The foam filling has two different sides, so that it is relevant that the "right" side up. From the outside, but you can not realize how rum you have to put the mattress.
