A respiratory interface in combination with a headgear assembly, the interface comprising an inflatable soft compliant seal member adapted to cover a nose and a mouth of a user, the seal member comprising a sealing portion that is adapted to contact a face of the user, the sealing portion comprising a rolled perimetric edge and a sealing flange that extends inwardly from the perimetric edge, the sealing flange comprising an extended surface that has one end connected to the rolled perimetric edge, a support member secured to the seal member, the support member being more rigid than the seal member, the support member comprising a support member perimetric edge, the rolled perimetric edge of the sealing portion extending outward beyond the support member perimetric edge and a generally vertical medial plane dividing the interface into a right half and a left half, the interface being more flexible about the generally vertical medial plane than about any generally horizontal plane that extends through the interface, the headgear assembly being substantially inelastic and connected to the support member of the interface to provide a substantially inelastic connection between the headgear and the interface.
