Abstract
A multi-dimensional pillow comprising a core having a cross sectional thickness gradient along one dimension and at least one geometric piece attached to the core parallel to the direction of the thickness gradient. When the user is in the back-lying position, the geometric piece maintains either the normal lordotic curve of the neck or flexion of the neck and the thickness gradient biases the head in the downslope direction causing a controlled rotation of the head resulting in a traction effect on the upslope side of the neck. The traction effect is due to the coupled easy natural biomechanical motions of side bending and side rotation of the neck to the same side.
