The nasal cushion is supported by the mouth cushion, does not contact a bridge of the patient's nose in use, and extends at least partially into the breathing chamber. A patient interface system includes a patient interface structure and a patient interface structure positioning system configured to position, stabilize and secure the patient interface structure in sealing engagement with the patient's face.
