Since I always had with my old mattress feel like lying in a hollow, and a really good night's sleep does not necessarily wanted to hire, I decided to buy me a new mattress. With discussions in shops, I have unfortunately not had good experiences, but to fight on the Internet through the almost limitless range, was not exactly easy. Ultimately, I decided due to good customer and Stiftung Warentest reviews for this Irisette mattress. Delivery by Amazon as always was fast. Since the mattress for transporting welded u. Was compressed so that they take about 1 day to regain their volume back to what it also creates almost (20 cm's not). The smell will disappear after about 1 day, which unfortunately is not the case. While it's not unbearable, but probably has the reference but only once in the washing machine to differently to "smell". Now for the support characteristics: the mattress is very soft, in fact, which is of course used to. The body weight is distributed in the loungers but quite good on so that you can not by lies (who, however, reaching out to 80 kilograms should perhaps think about H3 (?)). In the shoulder area, I find it turn a little too hard (I am primarily side sleepers). Otherwise, it adapts relatively well to the body contours - at least better than my old M. - but I am also feel that this adjustment decreases the longer you lie on the M.. In conclusion I would say that although the M. was not a bad buy, but is also not 100% convincing.
