I have the mattress ordered directly from the manufacturer (and via Amazon Payments paid, very comfortable) and two days later she was already delivered by DHL, not to the home, so my only 1.55 meters tall friend had their hands full to heave the almost as large cardboard box to the 4th floor. The mattress makes a very valent impression of light, chemical smell after 3 days was no longer an issue. Actually, I lie comfortably on the mattress, but I have the impression that possibly H2 would be better suited for me. I have with my 100 kg body weight sometimes pain in the side position. Stiftung Warentest had once written that the foams in the production in the different areas have different hardness due to the different density. Therefore mattresses can sometimes be more severe and even softer than it indicates the degree of hardness. Perhaps this explains the occasional reviews of the mattress, which hold despite H3 for way too soft. I'll probably buy soon for my girlfriend H2 variant, so we sleep again in the future at the same level :-)
