For comfortable side sleeping you need between 4" and 6" of medium - firm pillow support to help you establish and maintain proper spinal alignment. Most pillows don't provide that much, which is why people wake up to punch and fold their pillows.

Serenity Pillows side sleeper pillows have two chambers. The bottom is filled with organic buckwheat or millet hulls for unsurpassed support. As your head nestles into the pillow, the hulls flow outward to the edges, molding effortlessly to your contours. The pillow's unique box shape casing allows ample room under the neck for the filling to accumulate and provide form-fitting, soothing support.

The top is filled with pure, soft, Eco Wool for luxurious comfort. The addition of wool distinguishes Serenity Pillows from other buckwheat hull pillows that can feel especially hard on your ear when you are on your side. (US PATENT 6,701,555)
