I have the mattress now. Now 3 weeks use, and it is still a dream Not too hard, not too soft, just exactly fits. There is no annoying "chink" more, in my view, a great advantage. And yet she also has no moorings or anything lost (height, Soft, Härte..alles remained the same). Although I was skeptical to order a mattress on Amazon, but I am pleasantly surprised and above all absolutely convinced of this mattress. Definitely worth a buy.
