The MedCline Acid Reflux Relief System offers relief from painful, nighttime acid reflux so you can sleep better at night and feel better during the day. This patented Sleep System is the only product on the market today that creates and maintains the doctor-recommended inclined, left-side sleeping position in one simple solution for effective, natural acid reflux symptom relief. It delivers all-night comfort by raising your entire torso and esophagus 15 to 20 degrees to reduce painful nighttime breakthrough GERD symptoms. With a patented arm pocket to remove pressure from your downside arm and shoulder, the therapeutic body pillow, and smaller insert pillow, you will sleep comfortably each and every night. Proven to reduce exposure to harmful stomach acid 87% better than a bed wedge. Sleeping on Acid Reflux Relief System protects against the long-term health consequences of untreated nighttime reflux, such as Barrett's Esophagus or esophageal cancer, without stacking pillows or sliding down a bed wedge. Available in three sizes to ensure proper torso fit. The small size is recommended for those who have a height of 4' 8 through 5' 4. Components are compressed for shipping. Once decompressed, fluff the body pillow and insert pillow vigorously and to help regain their shape. MedCline can be slept on immediately but can take 72+ hours for any residual new memory foam smells to dissipate. Foam typically takes about 30 nights to break in and meld to your body. All system components come with removable, washable cases installed.
