A method of manufacturing a cushion for a respiratory mask includes providing a mold with at least two mold halves and at least one core therein, closing the mold, and injecting a first material into the mold to form the cushion. The at least one core is enclosed by the cushion thereby forming at least one cavity. The method also includes opening the mold, removing the at least one core from the cushion to provide the at least one cavity within the cushion, and sealing the cavity. The cushion includes a support plane configured to be supported on the patient's face in use. The at least one core is arranged in the cushion with a C-shape on a plane substantially parallel to the support plane.
