Abstract: Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patient's respiratory cycle in use. The positioning and stabilising structure may comprise at least one gas delivery tube to deliver the flow of air to the entrance of a patient's airways via the seal-forming structure. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of a length of the at least one gas delivery tube to enable the positioning and stabilising structure to fit different size heads.

Abstract: A patient interface to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to the patient's airways to ameliorate sleep disordered breathing includes a frame assembly and a cushion assembly configured to removably and repeatably connect to the frame assembly. The frame assembly and the cushion assembly form at least part of a plenum chamber pressurizable to a therapeutic pressure. The cushion assembly comprises a one-piece construction including a seal-forming structure configured to form a seal with a region of a patient's face surrounding the entrance to the patient's airways and a frame connection structure configured to removably and repeatably connect the cushion assembly to the frame assembly. The seal-forming structure comprises a first elastomeric material and the frame connection structure comprises a second elastomeric material, the first elastomeric material comprising a lower durometer or hardness than the second elastomeric material.
