The frame comprises a set of fasteners for removably coupling the headgear to the frame, the set of fasteners comprising first and second fasteners and third and fourth fasteners, the first and second fasteners configured for fastening and positioning respectively the first and second strap ends of the headgear on a first side of the frame, and the third and fourth fasteners configured for fastening and positioning respectively the third and fourth strap ends of the headgear on a second side of the frame. The frame comprises a connection port for receiving an air circuit; and a cushion including a cushion support structure to which the cushion is adhered. The cushion support structure is adapted to removably couple with the frame, the cushion configured as a substantially under nose seal portion and a mouth seal portion, the under nose seal portion comprising a sub-nasal ridge formed as a sealing boundary about both nares of the patient for achieving a seal in the sub-nasal region. The cushion is configured to roll inwards and close around a periphery of the nares.
