Is there a downside to sleeping without a pillow?
How do I know what height pillow is best for me?
The height of your pillow should depend on your sleeping position. If you sleep on your side, you should use a pillow that is higher under your neck than your head. If you sleep on your back, you should use a thin pillow, and if you sleep on your stomach, you should use no pillow or a very thin one.
