A rubber pouch in the lumbar area of the backrest inflates by a hand-pump adjuster.
Extra foam is added to the lumbar area of the backrest, to provide a stronger, more pronounced, lumbar support. 
The foam lumbar support in the chair backrest is reduced to provide a less pronounced, more neutral lumbar support. 
The black plastic outer of the chair backrest is fabric covered – usually to match the seat and back upholstery.
