The mother of all pregnancy pillows^®
The Leachco Snoogle® Original Body Pillow by Leachco will meet all your sleeping needs.  

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, 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 removable/washable cover. Patented.
