This neck pillow is designed for ultimate travel comfort. Its U-shape and memory foam construction provide excellent support for your head and neck, preventing forward leaning and relieving pain during journeys. The pillow measures 11.8*11.8*3.94 inches. The crystal velvet pillowcase is soft, breathable, and resistant to pilling and fading. We've optimized the shape through multiple experiments to better fit the cervical vertebrae, with enlarged sides to prevent head slippage and reduce fatigue. For convenience, it features a hanging buckle, allowing you to easily attach it to your luggage when it's full. Adjust the comfort for your car, plane, or home use. We offer worry-free after-sale service and are committed to customer satisfaction. Please feel free to contact us if you have any issues.
