How long does it take to adjust to a new pillow?

Are there downsides to cervical pillows?
The primary downside is a lack of versatility; cervical pillows are usually designed for specific positions and are not “all-rounders.” Additionally, they can feel quite firm or restrictive to people who enjoy moving their arms under their pillow. The fixed shape also makes them difficult to use for sitting up in bed.
