Nundenn, on the mattress you really could not sleep well and even after almost 2 weeks was no improvement, so I was about to dispose of the mattress. But then I came by chance to this viscoelastic circulation of FMP. Due to the positive feedback from other buyers, I decided also to buy, although some skepticism was present.
I have the support now for about 2 weeks and am very satisfied! Had not thought that these viscoelastic mattress can enhance my terrible mattress. The advantage is clearly on the material, since this relieves the spine and one quasi "sinks", but very pleasant. This is a quiet and restful sleep is granted.
A suggestion I have yet: The installation of "loops" on the corners, so that the mattress can no longer slip, since that is with me unfortunately after a few days the case. Despite Spannbetttuch.
