I myself am tummy sleeper and weigh 75kg. Generally you should grab as Bach to sleeper harder mattresses, for which I have decided on the hardness H3.
After seven months, I'm just as comfortable as the first day. Rarely have I had such a comfortable mattress. Depressions are formed not with me.
But to complain about is the reference. This is actually very cheap. He is in no way comparable with the remuneration of Schlaraffia and Co. I still prefer a Molto pad over the slipcover, this is not so strongly stressed. After washing three times the cover, I assume that he was still holding at least five years.
With regard to the length of the mattress, so it is right that it measures less than two meters. However, this is often the case in mattresses (even expensive brands), so that they fit well in the bed frame.
Should I on my "Dream Night" the next 3-4 years just to sleep comfortably as before, this price was still outstanding.
Dear exchange after 4-5 years the mattress, as I keep a twice as expensive for eight years. I find that much more hygienic.
