A patient interface includes a seal-forming structure constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways. The seal-forming structure comprises a first section and a second section. The first section is constructed from a first material. The first section is configured to sealingly engage against a first region of the patient's face. The second section is constructed from a second material that is different than the first material. The second section is configured to sealingly engage against a second region of the patient's face. The second material is foam. The patient interface also includes a positioning and stabilising structure to provide a force to hold a seal-forming structure in a therapeutically effective position on a patient's head.
