The U-shaped pillow is a wrap-around pillow shaped like the letter “U” and is designed to provide neck and head support. It is often used when sitting for long periods of time or traveling, and can effectively relieve neck fatigue and avoid head tilt or unnatural postures. The U-shaped pillow is particularly suitable for use when riding in public transportation, and can also be used as an auxiliary pillow when sleeping to provide better comfort and support.
