The Topstar SITNESS AirWork office chair is characterised by its breathable backrest with height-adjustable lumbar support and the colour-coordinated design of the seat and backrest. The integrated 3D SITNESS movement technology allows additional movement while sitting.
The spring tension automatically adjusts to the user's weight and can be fine-tuned via a rotary crank if required. The synchronous mechanism complements the 3D seat movement and offers various options for individual adjustment. The backrest tilt can be set in four stages via a travel limiter. A sliding seat enables adjustment of the seat depth.
The comfortable contoured seat complements the seating features. The armrests can be adjusted in both height and width. This provides various adjustment options for the seat, backrest and armrests.
The black plastic star base is equipped with load-dependent braked twin safety castors for carpeted floors. All plastic parts are manufactured with a proportion of recycled plastic and the individual resources can be separated. The product packaging consists exclusively of cardboard or recycled paper.
