This pillow doesn’t look like what you would expect, thats because it was designed by an Ergonomic Designer in consultation with a Doctor of Chiropractic. One of the key goals to sound sleep is Spinal Alignment which can help you to be more comfortable. Because people sleep on their backs, sides, or both, this pillow was created to work for each sleeping position. The ergonomic design offers comfortable support and stability in all sleeping postures. The result is a more sound sleep and less tendency to wake with pain, stiffness and many of the symptoms resulting from lack of support.
