Replacement cushion for Resmed Quattro™ FX & Quattro™ FX For Her Full Face CPAP Masks. Select from small, medium, and large. Cushion only, mask and headgear sold separately.
The dual-walls consists of an inner, supportive layer that stabilizes the cushion and a softer, outer membrane that reduces the likelihood of leaks and pressure sores. As air flows through the cushion, the outer membrane rolls and inflates around the nose rather than stretching over it.
