The MedCline Shoulder Relief System eliminates chronic shoulder pain at night for a better night's sleep. This Sleep System allows you to once again sleep comfortably on your left or right side by dropping your downside arm into a patented arm pocket to remove shoulder pressure while draping your other arm over the Therapeutic Body Pillow creating a neutral arm position. It is expertly designed to offer all-night comfort and support your healing path, whether your shoulder pain is a chronic struggle or the result of an injury. The three-component Sleep System gently supports your entire body, lifting, and alleviating the pressure you had typically put on your shoulder while you sleep, which may keep your nighttime symptoms from getting worse. The Shoulder Relief System creates an approximate 10 degree angle, which is ideal for rotator cuff injuries, arthritis/bursitis, nerve impingement, post-surgical recovery and general shoulder pain. The patented arm pocket at the top of the Sleep System is symmetrical so that you can sleep comfortably on your right or left side. The Therapeutic Body Pillow can be used with the long limb in front of you or behind you, depending on what you find to be more comfortable. The flexible design allows you to position your arm however you normally would, either out straight onto the bed surface or tucked up under the Body Pillow. This flexibility gives you the freedom to find a posture that is most comfortable to you while enjoying shoulder pain relief while you sleep. The large size is optimal for those who are 5'10 and taller. Components are compressed for shipping. Once decompressed, fluff the body pillow and insert pillow vigorously to help regain 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 components of our shoulder sleeping pillow system come with removable, washable cases installed. TAA Compliant.
