Kinesit is the first task chair produced by Arper. It comes with an integrated mechanism which allows for a synchronized movement and controls for the adjustment of the heights. Both systems are hidden under the seat. An adjustable backing for a lumbar support is also integrated and hidden inside the backrest, guaranteeing a further support without making the backrest thicker. The backrest is available in three heights and Kinesit comes with or without armrests. It can be upholstered in stretch mesh, leather or fabric in the various sample colours.
