An energy absorbing lumbar seat insert for a vehicle seat is provided. The seat insert provides support for the user's lumbar area. The insert is preferably composed of high-density, energy absorbing polymerized material such as a polyurethane. Alternatively, the insert may be composed from other polymerized materials, including polyethylene, polypropylene, and polystyrene, or any combination thereof. The insert may be made of a single polymer or a mixture, or may be composed of multiple layers of two or more different polymers. Attachment of the insert to the seat back may be accomplished by chemical or mechanical fastening. The insert may be molded to conform to the profile of the lumbar region of the back of a particular driver.
