Someone wrote that he let the mattress air out first because of the smell. I did not have this problem, it did not smell and after unpacking landed the mattress on the slatted frame and was immediately taken into live operation.
I weigh 118 kg and feel in good hands here with H3. Previously I had a H4 mattress that was clearly me too hard. I often had backache because I'm side sleepers.
After a few days here now my impression of the Irisette Lotus ... It is good. The hip is reduced in side position comfortably far one, not too far. I think my backbone is reasonably straight and the back pain will then probably subside soon.
Somewhat critical, and why 4 instead of 5 points, I think the so-called 7 zones, which should be in addition to the pelvic area, the shoulders sink into side position somewhat. I can find so limited. In the shoulder area I would have liked to have had a bit softer.
Overall, a good product. I would recommend the mattress without hesitation at all times, a sample higher than one or two nights then clarity about the always very individual feeling.
