A spinal treatment system includes a traction device, an exercise device adapted for imparting curvature to the lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force, and a cushion coupled to the traction device and configured to bear against one or both of a head of the user and the thoracic spine of the user. The exercise device includes a frame for placement on the floor. A pad or inflatable bladder is carried by the top surface of the frame. A body strap attachment portion encompasses the thoracic-sacral spinal vertebrae region of the user and secures the frame to the user. The cushion includes one or more pad sections or inflatable bladder sections.
