The Chiropractic neck pillow or ChiroNeck Pillow wraps around your neck with an additional firm column included at the neck band to provide added support to the neck. Those people with sensitive necks or who visit doctors or chiropractors for chronic neck problems may benefit from the extra neck support. The ChiroNeck pillow is also perfect for recliner chairs, sleeping in bed, or in the car, airplane, bus or train while traveling. It contains a special supportive column filled with flax seeds for enhanced neck care without sacrificing comfort. This size is for people with neck circumferences of 15 - 17 inches. Most people in the population can use this. The pillow is narrower and softer at the cervical area and will easily fit in the small space between your neck and the head rest in the car or on airline seats. The pillow's enlarged chin rests provide forward support to prevent head-nodding while you nap. The zipper opening allows for easy adjustment of the filling material depending on your personal preferences for comfort.
