What does this product do?
This desk swivel chair supports you during long periods of sitting thanks to a special Body-Balance-Tec joint that promotes an ergonomic seating posture. The chair is designed as an Orthositz, which means it specifically contributes to a healthy body posture while working. You choose this chair when you spend many hours behind a desk and want to deliberately invest in back support.

Why this size and version?
With seat dimensions of 440 x 400 mm, this chair offers sufficient seating surface for most users without taking up too much space. The seat height is infinitely adjustable between 430 and 510 mm, so you can perfectly match the chair to your desk and height. The steel five-star base provides sturdiness and stability during use.

The Body-Balance-Tec joint explained
The Body-Balance-Tec joint is the distinguishing feature of this chair. This mechanism allows your body to make natural movements while sitting, which promotes circulation and reduces muscle tension. The backrest is adjustable in both height (200-300 mm) and depth, so you get support exactly where your back needs it.

If you use the chair on hard floors such as laminate or parquet, you can optionally order hard floor castors with code 70699950. The 100% polyester upholstery is easy to keep clean and retains its colour with regular use.
