Core Products International, Inc. was founded in 1988 with the idea that therapeutic products should be comfortable to wear and use. It all started with Phil Mattison’s sore neck, which drove him to see a chiropractor. Upon learning his discomfort stemmed from an improper sleeping position, Phil worked with his chiropractor to develop a new kind of spinal-support pillow. The result was the Wave Comfort® Pillow, an innovative therapeutic foam pillow with waved edges for added comfort. Over the next few years, Phil evolved the Wave design into a fiber cervical pillow called the Tri-Core®.
