A patient interface assembly that includes a patient interface device, a headgear, and pivoting coupling member joining the interface device to a headgear assembly. In one embodiment, a spring biases the patient interface device against the patient's face when in use. In a further embodiment, the patient interface device is a nasal cushion that includes a formable support mounted to the nasal cushion for providing support and adjustment of the nasal cushion to improve fit and comfort. The headgear assembly in one embodiment is a semi-rigid, minimal contact harness assembly and includes an adjustment assembly that allows for a simultaneous adjustment of multiple straps. In a further embodiment, a pair of rigid connecting members couple the patient interface device to the headgear.
