The Ultimate Cervical Support Pillow combines the best features from fiber and foam pillows to create the ultimate pillow for support and comfort! This non-allergenic foam pillow provides proper alignment of the neck and supports the head while sleeping to help alleviate headaches and neck pain. The orthopedic design helps relieve a variety of conditions affecting the neck and shoulders. It is also ideal for CPAP users. For back sleeping, choose from one of the four distinct neck roll supports to find the one that fits your body and neck best. The shaped center gently cradles the head for comfortable sleep. Increase or decrease the amount of support by simply rotating the pillow to a larger or smaller neck roll. Gradually increase cervical correction by using a larger roll. If at any time you experience increased neck pain, reduce the amount of support by using a smaller neck roll or a traditional sleeping pillow. For side sleeping, large side sleeping areas with two distinct heights help keep the head level for proper alignment of the spine. These side surfaces feature airflow channels which gently cushion your face and ear for comfortable sleep. Channels on each side of the pillow help reduce pressure on the jaw, making it more comfortable for people with TMJ or jaw pain. For side and back sleepers, enjoy a smooth transition when moving from side to back sleeping or vice versa. Plus, you will benefit from all the features designed specifically for back or side sleeping. For CPAP users, a distinct edge allows a CPAP mask and hose to comfortably drape over the side of the pillow. This helps prevent mask and pillow interference and keeps the CPAP mask from moving or placing excessive pressure on the face. The Ultimate Cervical Support Pillow's unique molded foam provides a firm foundation with a surface that is soft to the touch. The pillow comes with a machine washable, soft, fitted, zip-open cover that is easily removed for washing. 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. Head cradle is not intended for side sleeping and may cause neck pain.
