Introducing Kinesit, Arper’s first office chair that is one hundred-percent compliant with regulatory requirements. Light and minimal in design, the chair seat and back are fully adjustable allowing it to conform to individual body types for optimal comfort, even during more time consuming projects. The chair features a built-in mechanism hidden discreetly under the seat that provides synchronized movement and seat height command. An invisible, adjustable lumbar support is concealed within the backrest’s thin frame to give additional flexibility and comfort.
