If you are like most people, one pillow throughout the night is just not enough. There's the pillow that goes behind your back for support, the one between your knees for temperature control and the two to prop up your head to aid in breathing. And, if you're pregnant... don't forget to add one more for tummy support. The Snoogle is uniquely designed to follow the natural contour and shape of your body from head to toe. Perfect for sleeping, relaxing and even nursing baby. Complete with easy-off zippered removable washable cover.
