ResMed's Dual-Wall Spring-Air full face cushion distributes pressure evenly and absorbs even the slightest user movements, so users can enjoy a good night’s sleep, confident that their seal is safe. The suspension-like combination of the Spring Air cushion and Spring frame means forehead support is unnecessary. Eliminating an additional point of adjustment, fitting Quattro™ FX is fast and straightforward. Available in small, medium, and large sizes.
