Quick Answer
The FSA cervical pillow is an ergonomic sleep accessory designed to promote neutral spinal alignment by cradling the head and supporting the neck. It typically suits side sleepers and back sleepers who prefer a structured, medium-firm feel over traditional plush pillows. However, the key limitation is the adjustment period; most users require 7 to 14 nights for their muscles to adapt to the contoured shape, and it is generally not recommended for stomach sleepers.
