Limitations and Considerations
While a king size cervical pillow offers structural support, it is not a universal solution.

Personal preference remains the most significant factor; what one user finds supportive, another may find restrictive. Importantly, there is no guarantee that changing a pillow will resolve underlying sleep or physical issues.
