Patent attributes
A vehicle seat assembly having a cushion composite attachable to a vehicle. The cushion composite has a structural layer of an expanded polymer and a cushion layer adjacent the structural layer. A trim material covers the cushion composite. The structural layer is proximate the vehicle when the cushion composite is attached to the vehicle. A surface of the structural layer defines a cavity extending into the structural layer. An opening of the cavity is disposed proximate the vehicle when the cushion composite is attached to the vehicle. The cavity is configured to facilitate flexure of the structural layer when a force is applied to the structural layer.
