Quick Answer
A cervical pillow is an ergonomically shaped sleep tool designed to support the natural curve of the neck. It typically features a contoured design with a higher loft on one side and a lower loft on the other. It may suit individuals who struggle to find a neutral neck position while sleeping on their back or side. However, comfort is subjective, and these pillows are not a universal solution for sleep quality.
