Abstract: A portable harness that wraps around the rib cage and thoracic spine is disclosed. Unlike other harnesses, the present invention has an extension allowing it to be suspended above the user's ribcage to apply an upward pull. This suspension strap provides a distracting/unloading force on the lower back by holding the upper torso in place while the weight of a patient's lower body creates traction on the lumbar spine. The harness can be used with any chair back, including office chairs, or vehicle seats. This allows people with lower back pain to sit more comfortably while sitting in a regular chair, driving a car, or flying in a plane. This will decrease low back pain since sitting for long periods will no longer compress the lumbar spine, it will actually be therapeutic by allowing a person to sit in an unloaded position.
