The cervical memory foam pillow is designed to provide more support and comfort to the necks of people who are sleeping on their side. As you sleep at night, your body will naturally use gravity for its natural process of muscle relaxation. When your head is resting on the pillow, it can cause pressure that could potentially lead to a sore neck in the morning. The cervical memory foam pillow works by using a contour design that mimics the shape of the human neck, providing traction and stability while also keeping air away from key pressure points on your neck during sleep.
