I have to use this pillow or I don't sleep at night.  I've been using this product for over 6yrs. and finally needed a new one. I originally purchased my first one in a chiropractors office. I have severe osteoarthritis in my neck area and this pillow has helped to alleviate the pain and lets me get a good nights rest without all the tossing and turning.
They are definitely worth the money and the quality is excellent.  I will be purchasing the travel size so I don't have to take the larger size everywhere I go.  I was happy to discover you were still selling the products online.
