Patented and doctor designed, this pillow improves sleeping posture by correctly aligning the spine for back or slide sleepers. Contoured design helps prevent a chin-to-chest position, opening airways and reducing airway obstruction, which is a major cause of snoring. The Snore-No-More pillow also promotes deeper, more restful sleep. Soft urethane foam cover that fits standard pillowcases. Size: 16" x 22".
