Just as a good mattress should be. Support the body where it is needed and elsewhere be more flexible. I am a pretty tough nut to crack, so for me "H4" the measure of all things. Who now believes but the mattress was hard as a board, is very much mistaken. She's just not as flexible in its core. A kind of progressive damping, but without being here felt somewhere as hard. It is sometime just not anymore. - I've never slept so well and happy in my own bed. - They also isolated very well, now is the winter, it is outside of the double-digit growth in the sub-zero temperatures at night and I sleep with the windows open. But from below penetrates no cold in my bed. We'll see if it proves itself just as well in the summer, there really is no reason why, because what insulates against cold also helps against external heat.
