A key feature that is often overlooked in a pillow, is the ability to change its height.
I have sold (and used) a height-adjustable pillow for years and swear by it. It really makes the pillow a lot more versatile.
When you are looking for a new pillow, consider one that is height adjustable, it could make all the difference.
In the practice here, I sell the Chiro-Pil-O, if you would like to see one, feel free to pop into the practice and see it for yourself.
