The cushion meets the properties described. I think for me it is a bit too high. It is 15 cm high and since there is more dimensionally stable compared to a feather pillow, it acts in lying quite "impressive" and at the 1st drauflegen I had the feeling: too high, too tight and I sink hardly any. But this was the time and because I mean known neck tension (no matter which pillow I took) no longer have, :-) it must have but brought something.
At first it smelled strictly, nor for chemical / plastic, which I believe has also eased somewhat.
