The mattress was delivered very quickly and with very good service. I always wonder about 7-zone mattress, because where at me the Po is (50m height) are located at a large man or the waist, is where they should be compliant with me would have a great person she "firmly" have. How can one work out for all applicable 7-zone? In the shoulder area they should be flexible? But where there is head-and footrest? Then I found no evidence. Now I have a pocket spring mattress hardness 2 and when I sit down on the bed I fall always down to the frame down what is-but uncomfortable with the described foam mattress I sit at the edge of the bed as if on a kitchen chair firmly and without any flexibility. That's how I was then. After 15 minutes, the feeling was to lie on a board unbearable. A whole night I could not bear. I returned the mattress, where the seller was very accommodating and friendly. Kudos to Easy-Sleep 24, but unfortunately not buy recommendation. Unless you listen to the advice of some fellow overtook that hard chairs for the spine was best. Then I wish "good night"
