What are the best pillows for back sleepers?

Choose a pillow that is not too firm or too high as you want your neck supported with your head at the same level as your upper spine. Typically this is a low to medium profile pillow depending on your frame size.

According to an article by Harvard Medical School, a rounded pillow with built-in neck support that supports the natural curve of your neck and an indentation for the neck is a good way to go.
