The hardness H3 was just right for me (84Kg weight, at 1.90 m size). Not too hard and not too soft, it is easy to do it wonderfully.
The mattress makes an impression of quality and the cover is washable, is clearly a plus.
One reason why I bought this mattress is that I've got on my old mattress back pain.
On this mattress I sleep now been a few months without pain.
But to the zones, I can not say much, I have just tried it by pressing to find the different zones, I was at the end but not sure if and where are located!
However, there is also a reason why I have to deduct a star. The mattress has begun after about 1.5 months to lint, usually not bad, but the lint were so thick that you could see through the sheets. I've sucked then, unfortunately, some lint were still connected to the material of the mattress, as only tear and suck helped. Cost me half an hour, let's see how long it takes to get new lint formed.
Conclusion: On the whole, a good and comfortable mattress, but that Gefussel not have to.
