The Derila Ergo Pillow works by promoting proper head, neck, and spine alignment, helping reduce physical strain and support deeper, more restorative sleep. Its ergonomic contoured design follows the natural curve of the cervical spine, preventing the head from tilting into uncomfortable positions that often cause neck pain, stiffness, and morning discomfort. By maintaining correct posture, the pillow also helps keep the airway open, which may reduce snoring and sleep disruptions.
