The combination with a 27cm high mattress H3 RG55 and 5cm of visco-elastic pad in H2 is the ideal combination for me. In particular, therefore, as I despite being overweight and Visco Pad can turn me in bed and not in the edition "stuck". I've seen at fixedly mounted on mattresses visco-elastic supports and that is why I have also spoken out long against this requirement, however, has made me really happy. Please consider that the combo that I have, so only makes me happy, which may be entirely different for another person with other conditions.
I give absolutely justified 5 star.
Update, almost 3 months later (August 2012): I can still only say good things about the rest. Meanwhile, I have the feeling that I can not sleep without this requirement, so I got used to it. I am almost afraid that if I have to stay once in a hotel or with friends / will that I will rather miss my edition. One can set up under his arm at the hotel / bad friends with a 140x200cm Edition. Still 5 stars from me.
