Abstract
Abstract A multi-segmented cushion assembly, positionable upon a contoured dental chair, supports a child at the proper height with respect to the dentist and maintains the head of the child tilted back while precluding side-to-side movement of the head. By being segmented, the cushion assembly can be altered in plan form to accommodate a range of torso lengths of young children and yet provides a feeling of comfort and security to the children.
