The present invention discloses a positioning and stabilising structure for a patient interface, the positioning and stabilising structure configured to provide a force to hold a seal-forming structure of the patient interface in a therapeutically effective position on a patient's head, the positioning and stabilising structure comprising: one or more gas delivery tubes to receive a flow of air from a connection port on top of the patient's head and to deliver the flow of air to an entrance of the patient's airways via the seal-forming structure, each of the one or more gas delivery tubes being constructed and arranged to contact, in use, at least a region of the patient's head superior to an otobasion superior of the patient's head, each of the one or more gas delivery tubes comprising: a superior tube portion configured, in use, to overlie a superior region of the patient's head, the superior tube portion comprising: a first end configured, in use, to overlie a superior portion of the patient's head at or proximate the sagittal plane of the patient's head; a second end configured, in use, to overlie a side portion of the patient's head; and one or more stiffened portions between the first end and the second end configured to provide a higher resistance to relative movement between the first end and the second end in an anterior and/or posterior direction than in a superior and/or inferior direction in use; and an inferior tube portion configured to be connected between the second end of the superior tube portion and the seal-forming structure in use.
