The Boppy Pregnancy Wedge with Cotton Slipcover is a wedge shaped pillow that you place under the baby bump as you sleep on your side. By supporting the weight of the bump, it takes pressure off your back. It can also be used as a back support pillow.

The pillow is pretty firm, and you might need some time to get used to it. It can also be used to support your back when you sit up in bed or sit on a sofa.
