Abstract
A pillow of resilient material has a generally rotatable portion (cervical roll) for supporting the cervical region of a user. With a user's neck received across the pillow cervical roll and the user's head received on the pillow, rotation of the cervical roll in conjunction with collapse of angled chambers defined within the resilient pillow establishes traction in the cervical region of the user. Once its internal chambers are essentially fully collapsed, the pillow provides a generally continuous support medium for optimized resilient support of the user's neck and head, while maintaining a degree of cervical region traction with natural cervical curvature achieved through curved support of the user's cervical region across the cervical roll of the pillow.
