A cervical pillow is specially designed to help people that have neck pain when they are not sleeping. People who use these pillows can avoid the discomfort that comes with sleeping on an uncomfortable pillow, or one that causes further injury. A cervical pillow has a curved profile and is made from soft materials like down or foam. It helps support the neck, relieve pressure, and avoid excess movement. It is typically filled with cotton, foam, or a combination of both. Neck pillows are pillows that rest on the neck and shoulders with one end resting against the head. They provide support to the neck, neck area, and shoulders. These pillows can be filled with feathers or synthetic materials like memory foam. The head and neck pillows are the ones that support the head, neck and shoulders.
