Product description
  • Back rest with actively breathing mesh cover and height adjustable lumbar support
  • Comfortable contoured seat for an optimal posture when seated
  • The height and width of the arm rests are adjustable
  • Synchronous mechanism with fine tuning and integrated 3D seat motion
  • Back rest angle can be set to 4 different levels using travel limiter
  • With sliding seat (seat depth adjustment)
The Topstar Sitness AirWork G office chair is characterised by its breathable backrest with height-adjustable lumbar support and the harmoniously coordinated design of the seat and backrest. The integrated 3D-Sitness movement technology enables additional movement while seated.

The spring tension adjusts automatically to the user's weight and can be finely adjusted using a crank handle if required. The synchronous mechanism with integrated 3D seat movement provides further options for customised adjustment. The backrest tilt can be set in four stages via a travel limiter. A sliding seat also allows the seat depth to be adjusted.

The comfortable contoured seat completes the seating features. The armrests are adjustable in both height and width, allowing further individual adjustment.

The black plastic five-star base is equipped with load-dependent braked twin safety castors for carpeted floors. All plastic parts are partly made from recycled material and enable the separation of the individual resources. The product packaging consists exclusively of cardboard and waste paper.
