The head is our sensory center. We should bed it gently and stably in equal measure - in a good position, on fine quality and preferably naturally.

The feeling of well-being is an important component for good sleep and because our sensory perception is particularly pronounced at the head, we need a comforting resting pillow.
In addition, there are also ergonomic aspects in the choice of pillow. For example, people with shoulder / neck problems should use a narrow pillow because the shoulder and head need a different level in the lateral position and the wider the shoulders, the stronger the pillow.
In general, most people should have several pillows, depending on their mood or condition, and that is why we make good quality pillows cheap, so that the choice is easier.
