A seat assembly is provided with a seat bottom and a seat back. A first actuator is oriented in a lower lumbar region. A second actuator is oriented in an upper lumbar region. A controller is programmed to operate the first actuator to adjust the lower lumbar region, and operate the second actuator to subsequently adjust the upper lumbar region to provide a seat assembly motion pattern. A third actuator is oriented in a thoracic region or a seat bottom region. The controller operates the third actuator to adjust the thoracic region or the seat bottom region after adjusting the lumbar regions to provide a seat assembly motion pattern. A plurality of sensors is provided on the seat back and the seat bottom to initiate the pattern in response to a lack of detected occupant motion to induce muscle activation upon an occupant.
