Abstract
A multi-layer cushion having a shaped base on which is positioned a resilient, cushioning layer. The shaped base is constructed from a supportive foam and has front and lateral bolsters. The cushioning layer is an inflatable air cell cushion having a flexible base and an array of individual air cells arranged in rows across the flexible base. Rows of cells around the perimeter of the air cell cushion are configured to provide comfortable transition areas between the bolsters and the air cell cushion. The cushion includes a cover that has a lower compartment for the foam base and an upper compartment for the air cell layer. The cover functions to keep the air cell layer in place on the foam layer.
