The coupling pillow prevents the weight of the head from pressing on the arm, so that it does not become numb. The curved contour of the pillow helps maintain the natural curvature of the cervical spine and neck contour. The central hollow of the orthopedic pillow effectively relieves tension or stiffness in the spine by promoting proper spinal alignment and alleviating neck, shoulder, and back pain. The pillow is suitable for side sleeping, face-down sleeping, back sleeping, and stomach sleeping.
