The reason why I have ordered this pillow was that neck support pillows are hard as a board, as a rule - and I do not like to lie on boards. :) I am side sleeper, but I turn now and then sometimes on the back. For both the Billerbeck is very well suited. Have it at the same time looked upon with a Tempur Original. When Tempur pillow I did not feel that the pillow under the body heat is more supple. Found the stiffness and the shape of the cushion and disturbing hinterlich when turning from one side to the other. The Billerbeck however, does have essentially the same curvature as other cervical pillow, the material is not as hard and unyielding, through the thick and soft cover you also get the feeling that they are at a very "normal" pillows. Nevertheless, the pillow supports very well. The neck is straight, the neck completely, without creating a gap between the pad and the neck is formed. Thus, now I wake up and no longer on with neck pain and headaches. What I had to get used to the first day, when I lay down on the pillow I had initially feel like lying on a rubber ball, as if the head does not sink but would sprung back from the foam. Probably but must be due to the support function. However, I have got used to it very quickly. One star deduction for the rubbery feeling sun and the feeling that the Tempur had a slightly better support function. Furthermore, the Tempur prevents its rigid shape better malposition, such as the inclination of the head Seitenschläferdie forward toward your chest. The latter would be theoretically possible in Billerbeck. Whoever tends to be bent should bear this in mind when purchasing. Of course there is not the pillow, which is equally well suited for anyone who does that leave only try himself. For me, however, the decision was made to Billerbeck.
