Rest assured that you'll sleep easier using the CPAP 2.0 pillow by Contour Products. Compatible with most CPAP, BIPAP, and APAP devices, this pillow helps minimize facial pressure and mask shifting. Ear depressions allow for maximum comfort, a concave center supports your head, and a crescent curve cradles and naturally rests on your shoulders--all while a tether helps keep your mask hose from tangling.
