Limitations and Considerations
It is important to manage expectations when switching to a cervical support tool.
- Positional Constraints: This pillow is largely unsuitable for stomach sleepers, as the raised lobes can force the neck into an unnatural hyperextension.

- Back Sleepers: The central cradle helps stabilize the head while the neck roll maintains the cervical curve.
- Ergonomic Explorers: Individuals who have found traditional pillows too soft and are looking for a firmer, more disciplined sleep surface.
