I myself am 1.90 m tall and weigh around 100 kg, and am really satisfied with the degree of hardness! I lie on this mattress really wonderful, even in positions to which there was no question in my old mattress. So today I fall asleep on the side or even on the back, which of course is wonderful for desselbigen from an orthopedic perspective.
One shortcoming was the mattress but then unfortunately. Even after a week airing outdoors they still smells quite strong synthetically. So much so that the clothes take on the smell of the mattress. So after 3 weeks sleep on it's getting less.
CONCLUSION: Although the mattress still "new" smell, but I sleep very well on it and also a lot better than on my old Schlarafia. The price performance ratio is absolutely outstanding. Half a star deduction there for but offensive odor during the first weeks. -> 4.5 stars
