Johnson Controls on Jan. 31 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 will be available for the 2015 model year. Conventional urethane foam pads are replaced with a 100% recyclable alternative that provides a 5-20% weight reduction. Applicable for first-, second-, and third-row seats, the technology provides a dramatically thinner, tailored seatback with up to a 20% reduction at the center of the seat and a 35% or more reduction in the bolsters. The active seating surface adapts to occupants of all sizes. Each spring unit is able to react independently, further improving seating life while giving occupants the right amount of support when and where it is needed, according to Johnson Controls.
