A nasal mask that moves as soon as you turn over will eventually wake you up. The TrueBlue cushion uses Auto Seal technology, which follows the movements of the nose and face to maintain constant contact without needing to tighten the headgear.

• The cushion stays gently pressed against the nose, even when the head changes position during the night
• The adjustable headgear adapts to head circumference and keeps the mask stable night after night
• The nasal design leaves the mouth and chin free, for a less cumbersome feeling at bedtime
