A posture adjustment system includes a set of sensors coupled to a chair on which a person may sit. The posture adjustment system gathers data from the set of sensors and generates a posture model that reflects a posture associated with the seated person. The posture adjustment system then determines corrections to the posture of the person that could, potentially, improve their posture. The posture adjustment system then indicates those corrections to the person, or, alternatively, applies a set of adjustments to the chair to cause the person to assume a new posture that reflects the posture corrections.
