A **cervical pillow** is a specialized orthopedic support designed to maintain the natural curvature of the neck while sleeping. Unlike traditional flat pillows, it typically features a contoured shape with a raised bolster for the neck and a recessed center for the head, which helps align the cervical spine with the rest of the back. By promoting neutral alignment, these pillows aim to alleviate pressure on the joints and muscles, reducing common issues such as morning stiffness, tension headaches, and chronic neck pain. They are commonly available in materials like memory foam or latex to provide a consistent balance of firm support and pressure relief.
