Replacement Cushion for Quattro FX Full Face Mask.
The Quattro FX Cushion is built for CPAP users who want a traditional full face seal. It delivers a familiar, secure full face fit.
Rather than focusing on flexibility or movement technology, the Quattro FX cushion emphasizes structure and consistency. The silicone provides a stable seal that holds its shape well across a wide range of pressures, making it a strong option for users who prefer a mask that feels anchored and predictable throughout the night.
