JLSUN Vertebra Pulling Therapeutic Pillow uses the shoulder and occipital bone as two supporting points while the weight of the head presses down the pulling board producing a curved force that fits the natural shape of the vertebrae. By pulling the narrowed intervertebral space and intervertebral foramen, tissues such as the spinal cord and nerves will not be stressed. The pillow will also effectively relieve pain by using magnetic therapy.
