The Cerv-Align Cervical Support Pillow has both the firm support of an orthopedic pillow and the comfort of a traditional sleeping pillow. Designed to help relieve headaches, neck pain, and muscle soreness, this pillow is commonly used to help manage a variety of conditions affecting the neck and shoulders. While back sleeping, the extra firm fiber filled neck lobe contours to fit the shoulders and provides even support across the shoulder line while the conventional pillow area comfortably supports the head. For side sleepers or those who prefer the comfort of a traditional fiber or feather pillow, simply rotate the support lobe away from the neck. The fiber filled area gently cradles the head with down-like comfort and can be used to adjust to sleeping on the firm cervical lobe.It may take some time to adjust to this cervical pillow and immediate overuse may increase neck pain. Those who slowly ease their way into orthopedic correction by alternating between this pillow and their current pillow achieve the best results.Select from two different lobe sizes for a custom fit. Covered with high quality cotton fabric for maximum comfort and durability. The Cerv-Align's exclusive fitting system ensures a proper fit for any body type. Fits a standard pillowcase.
