A cervical pillow is specially designed to support the natural curve of the neck and promote proper spinal alignment while sleeping. Made from materials like memory foam, latex, or high-density foam, it contours to the shape of the head and neck, reducing pressure points and alleviating discomfort. Its ergonomic design helps relieve neck pain, stiffness, and tension headaches by maintaining a neutral posture throughout the night. Suitable for back, side, and sometimes stomach sleepers, cervical pillows can improve sleep quality, prevent morning stiffness, and contribute to overall spinal health. Many models also feature breathable covers and hypoallergenic materials for added comfort and hygiene.
