Is the kySsen made of the same material as the kyBounder?

The kySsen is made of similar material to the kyBounder, also absorbing, but much softer because the head applies less pressure than the foot.

We have received a lot of positive customer feedback about the kySsen, but it also requires time to become accustomed to. It will take a few nights for your body to get used to the new way of lying and get the full benefit from it. The best thing is for you to test it and find out whether you want the thick or the thin side under your neck (preferences differ according to spine shape).
