To provide a textile seal-forming structure with multiple curvatures.SOLUTION: A patient interface includes a seal-forming structure with a textile membrane which has at least one hole so that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patient's nares and or the patient's mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patient's respiratory cycle in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.SELECTED DRAWING: Figure 12
