Abstract: A pillow having a pivoting butterfly structure with two cushions pivotably interconnected by a hinge element to pivot between an open position and a closed position. Each cushion has a hinge end adjacent the hinge element, and a connecting end disposed at the end of the cushion opposite the hinge end. A middle portion is located between the hinge end and connecting end of each cushion. The cushions have a relatively flat inner surface and a curved contoured surface that extend the length of each cushion. The contoured surface projects away from the inner surface and forms two peaks near the hinge end and connecting end of each cushion. Between the peaks, the contoured surface curves inward back toward the inner surface and forms a concave groove near the middle portion of each cushion. A cover encases both cushions and contours the shapes of the cushions.
