The most important quality for the relief of pain is that the material conforms to the exact contours of the head and neck providing a compliant passive support. This means that you have the same amount of support in all areas minimizing the stress on all areas of support. Other filling materials which compress, try to recover their original shape and this puts stress on the muscles of the neck. Other advantages of the buckwheat hull filling are the "cool in the summer, warm in the winter" insulating properties, the ability to adjust the size to your individual needs by removing or adding back filler so the pillow fits you just right. The filling also lasts for many years making the pillow the best value cervical pillow on the market. Long after other pillows have collapsed and worn out a buckwheat hull pillow will still be fully functional. Buckwheat hull pillows are also environmentally friendly - for each pillow put to use it will save the manufacturing of the synthetic filling for ten or more ordinary pillows.
