ResMed's AirFit N30i Cradle Nasal Cushions sit comfortably and unobtrusively under your nose, so it's easy to sleep on your side or stomach. Cradle Cushions have soft, frosted surfaces that feel more natural on the skin; and maintain a secure seal even at high positive airway pressure levels.
Sizing Information: Cradle Nasal Cushions come in four sizes -- Small, Medium, SmallWide, and Wide -- any of which can be used on any AirFit N30i Nasal Mask. If you would like to try a different N30i cushion size, simply purchase the cushion you prefer and install it on your existing mask frame. AirFit N30i Cushion sizes are indicated by large letters printed on the side of the cushion: a red S for Small, a blue M for Medium, a purple SW for SmallWide, or a gray W for Wide.
