A respiratory interface device, a cushion body and a cushion support assembly is provided. The respiratory interface device cushion body includes a nose bridge engagement portion structured to engage a user's nose bridge, the cushion nose bridge engagement portion movable between an un-deformed first configuration and a deformed second configuration. The cushion support assembly includes a faceplate and a pressure distributing assembly. A faceplate perimeter nose bridge portion defines a recessed tapered contour. A pressure distributing assembly includes a number of pressure distributing members. A pressure distributing member is disposed at the faceplate perimeter nose bridge portion and is structured to move between a first position, wherein the pressure distributing member maintains the cushion in the first cushion configuration, and a second position wherein the pressure distributing member maintains the cushion in the second cushion configuration.
