The rechargeable Smart Sensor Anti-Snore Pillow is the latest technology in the battle for a good night's sleep. Made of soft and supportive contoured memory foam, it features a built-in sound sensor that detects the sound of snoring. When snoring is detected, an internal air bag automatically inflates to increase the pillow height by 3", and then deflates immediately. This gentle nudge is usually enough to prompt the sleeper to change position and stop snoring! Features multiple settings for light or heavy sleepers. Works up to 8 hours on a full charge. Fits in a standard pillow case and also includes washable cover.
