The federation's decision to endorse the system was based primarily on independent testing of Nikken's mattress, comforter, pillow, and pad - all of which will now carry the WFC logo.
"We were very impressed with the results," commented WFC Secretary-General David Chapman-Smith. "In particular, the lead researcher was so taken with the pillow that he now uses it exclusively in his own house. He found the pillow helps with his neck pain and headaches, and said that the pillow would help individuals with these problems."
"We are very excited to be working with Nikken," added WFC President Dr. Anthony Metcalf. "The sleep system is of very high quality - one of the best that our organization has seen - and the Nikken mission of total wellness complements the mission of the WFC."
The WFC will also be partnering with Nikken on future chiropractic research and educational endeavors.
