Incorrect sleeping posture can be a big cause for neck, back and shoulder problems. So choosing the correct pillow is extremely important.

The right pillow should suport the natural curvature of your spine, by keeping your head, neck and spine in a neutral alignment.

In regard to shoulder pain it is especially important for side sleepers to have the correct pillow, to relieve pressure on the shoulder and ensure the weight of your body is not just being supported by the shoulder. The right pillow should be thick enough to create a straight line from your head and neck through your spine.
