Johnson Controls, a global leader in automotive seating, overhead systems, door and instrument panels, and interior electronics, announced that it has formed a development relationship with luxury mattress manufacturer Harrison Spinks to integrate pocketed coil spring mattress technology into an automotive seat concept called ComfortThin. The thin profile seats replace conventional urethane foam pads with a 100 percent recyclable alternative, and provide a five to 20 percent weight reduction. This technology will be available for 2015 model year vehicles.
