A common kind of headache is a cervicogenic headache. It usually starts due to the positioning, movement, or posture of the neck.
Sleeping with improper neck alignment might trigger this.
Made with Flexible Cylinder Joints that can contour to almost any position, the Coquet Joli™ CozyFlex Pillow provides ample support and alignment for the neck. As it is made with memory foam, using CozyFlex can be almost as good as sleeping on a bed!
Use it at home, at the office or the car. Protect the neck from awkward positions can reduce headaches.
