A mask system including a cushion adapted to seal with a face of a patient is disclosed. The mask could be used in a CPAP system. In one form an unobtrusive full-face masks system is provided which is comfortable and has a wide fit range. The mask system is constructed and arranged to be used on the person without requiring a forehead support. The mask system including a cushion, said cushion adapted to form a seal on the face of the patient in a nasal bridge region of the face, a side of nose region of the face, a mouth corner region of the face and a lip region of the face. The cushion is also forms a seal on the nasal bone of the nasal bridge region of a face below the nasion and above the cartilage of the nose. The cushion also includes at least one lateral stabilising portion adapted to direct a force against the side of the nose in the region of the nasal bridge. The cushion may include a sealing structure and a supporting structure. The supporting structure may include gaps or spacing in a nasal bridge region and/or a lip region. In the region of the mask at the side of the nose an inner wall has a cross-sectional profile that is a J-shape (Section B-B Fig. 127a) and in a region of the mask at the corner of the mouth the inner wall has a cross-sectional profile that is a sickle shape (Section I-I Fig. 127e).
