A self-centering posture seating device is adapted to induce proper posture in seated persons. Specifically, a back support member designed to provide resilient support selectively in the region of the lumbar vertebra of a seated person is conjoined with a posture seating device designed to provide resilient support primarily in the spaced-apart regions corresponding to the ischial tuberosities. The result is a "self-centering" posture seating device which is noticeably more comfortable when properly used than it is when improperly used.
