From the thickness ago both mattresses are the same, making them suitable for a double bed; as long as you do not "in Gräbele" is, because of course there to show the different degrees of hardness by a significant level between the mattresses.
Of the degrees of hardness mattresses should therefore perfectly match our body weights, but after a few weeks of critical comments criticized my partner irrefutably that their H2 mattress lot was too soft that they would, even after this adaptation period not really sleep well on it, and whether one could change the supply / return ...
To make the house blessing again, I have reviewed here mattress bought later in H3 also for my partner, because I was so far very happy with my H3; and the mattress in H2 is now my niece (7 years), which is highly commended, cold foam mattress hardly better than their previous 50 foam mat. I would say that the H2 is really too soft.
After I had a total of about 5 weeks very well and for a long time finally slept symptom-free (with a break of 3 weeks by a New Year's Eve) in the back and neck on the H3, which are refilled, H3 was delivered for my partner; and here of a star deduction comes into play:
The new mattress in H3 seemed much stronger and over the whole lying surface (widthwise, not the 7 zones lengthwise) evenly to be supportive; in German, I had a major Kuhle located within such a short time in my mattress, despite weekly rotating and turning over! But that would be me not -SO- noticed if I had not had the brand new H3 for direct comparison.
After mutual test it on "my H3" and "the new H3" has decided that they want to soft my "is superior" mattress as an intermediate stage between the H2 and have a lot of new H3 my partner; my mattress seems now to recover under their lower weight, and the new H3 also has not abated in recent weeks with me, as the previous one.
Long story short: We sleep on the Irisette Lotus H3 now both better than ever, and if you ventilate his bed properly and the mattresses regularly turns and turns, you have a very good pad; provided that the slatted frame including what is good. The removable and washable cover of the mattress is of course great, because sometimes I sweat heavily during sleep.
From me, saying - not necessarily - a "strong buy recommendation", but also - by no means - a "hands off" ... I would say: Prima mattress in the middle price range, but the same mattress in H2 can be even as Lightweight forgettable.
