Abstract: An orthopedic device which will provide adjustable and yieldable support to the lumbar region of the spine when a person is in a sitting position. It can also provide adjustable and yieldable support to the cervical region of the spine when the person is in a supine position. It can also provide adjustable and yieldable support to the lumbar region when the person is in the supine position. The device has a semi-flexible flat backing member placed behind an air inflatable bladder so as to direct all of the varied and yielding pressures from the air inflated bladder in a forward direction and directly against the spinal column. The inflated bladder presses against a flap provided in a foam rubber front layer to permit the adjustable yielding pressure from the bladder to be distributed evenly against either the lumbar or the cervical region of the spine.
