You can sleep on either side or on your back with the U-shaped pillow.

This pillow has the added benefit of keeping you from tossing and turning in your sleep.

These pillow are large, so you will need a queen or king sized bed to use them.[1]

Body pillows come in many different shapes. The shape you want will depend on your personal preference and sleeping style. Many body pillows are shaped like a letter U, which can wrap around your body. The U-shaped pillow works by letting your head rest at the top of the curve of the U, which fits snug around you at the curve of the U upside down. The separate arms of the pillow wrap around you, with one arm going down your back and the other going down your front.
