Positional sleep aids are products and devices that support or encourage sleeping in positions that can lead to more restful sleep. They are particularly beneficial for individuals dealing with sleep-related issues such as snoring, sleep apnea, back pain, and acid reflux.

Products for snoring, back pain, and acid reflux are available over-the-counter without US Food and Drug Administration (FDA) clearance. Devices for positional sleep apnea are FDA-cleared and available by prescription.

Positional sleep apnea is when airway collapse occurs more frequently when a person with obstructive sleep apnea is sleeping on their back (supine). Positional therapies can sometimes resolve positional sleep apnea on their own, or they can be combined with other sleep apnea therapies.

This positional sleep aids guide compares devices on parameters including how the device works, acclimation period, FDA status, prescription versus over-the-counter, price, power supply, weight, data recorded, dimensions, warranties, reimbursement, and more.

How It Works
Worn around the neck or chest, Night Shift begins to vibrate when the user initiates supine sleep. The vibration slowly increases in intensity until a position change occurs. Night Shift is also an intelligent, interactive monitor that measures sleep quality and the frequency of unhealthy loud snoring.  
1. Snoring detected 2. Head position detected 3. Airbag inflated 4. Turn the head to the side gently 5. Airway cleared 6. Snoring intervenedThe Sleep Noodle helps to provide positional therapy by using its foam insert to ensure comfort but sufficient support to maintain side sleeping. An industrial-strength hook-and-loop fastener ensures the belt maintains its connection while wrapped around the user. The latest version is the Sleep Noodle UP, which allows the user to wear the noodle in a horizontal or vertical alignment.Supports both side and back sleepers for optimal comfort.Designed by a board-certified sleep physician and worn around the upper torso, Zzoma treats mild to moderate positional obstructive sleep apnea and snoring by ensuring patients remain on their side while sleeping—normalizing sleep quality while minimizing nighttime disruption and daytime fatigue. Smart Nora turns any pillow into a smart pillow. The device monitors breathing and predicts snoring using AI, then creates a gentle and slow motion under the pillow. This gentle application of positional therapy stops snoring without waking up the user.
Acclimation PeriodAfter the first night of use, a patient will know if the device is effective, based on how many times he/she attempted to sleep supine and how quickly he/she responded to the vibrotactile feedback.Not specified14 days1 week~2 weeks3-14 days
