Replacement cushion for Resmed Quattro™ FX Full Face Mask. 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.
Both the frame and cushion of the Quattro™ FX are specifically sized. The cushion size must be the same size as the frame to function. Select from small, medium and large. Cushion only, mask and frame sold separately.
