As has already been reported in detail on this pillow, I want to be brief. I have bought in the past few years about 7 pillows (mostly Viscose cushion and which also high-priced pillows well-known manufacturers). None could convince me comfort her. After a short time I always did the ear hurt where I was because my pillows were all somehow too hard. On this pillow I sleep now for about a month. This cushion nothing hurts. I feel deeply and sleep better. The hardness and the height of the pillow can be infinitely controlled by the amount of water. To this end, my tip: take to fill distilled water. Then later in any gases pillow form cause annoying bubbling. For the quality of the cushion, the material, the super comfort and also reasonable price (which only a fraction of my most expensive pillow is was now disposed of) is there from me the note 1. By the way, my wife would have necessarily as a pillow now. She always sleeps on my when I'm on the night shift)
