Abstract
An internally supported cushion for a seating unit is provided. The internally supported cushion includes an internal structure that provides rigidity when used adjacent a back upright or a side upright of a seating unit. The internal structure generally includes a rigid core element that is sandwiched between foam layers. The rigid core element is approximately upright and extends in the lengthwise and widthwise directions of the internally supported cushion. A batting layer is positioned immediately beneath an upholstery covering to prevent the covering from contacting the internal foam layers, which encapsulate the rigid core element.
