When do you choose this product?
When do you need an office chair with a mesh back?

The mesh back of this Topstar Airwork provides optimal ventilation, keeping your back cool and dry during long working days. This type of chair is ideal for office workers who value comfort and breathability.
Why this size suits most workplaces
With seat dimensions of 455 x 410-485 mm, this chair offers ample space without taking up too much room. The moulded seat follows the natural shape of your body for extra comfort. The height is infinitely adjustable from 420 to 540 mm, so you can always find the right working posture, regardless of your height or desk height.
Synchro mechanism for dynamic sitting
The synchro mechanism means the backrest and seat move together when you lean back. This supports your natural movements and prevents a static sitting position. Your spine stays in its proper curve, which reduces tension in the neck and shoulders. This feature is especially valuable if you regularly alternate between focused work and relaxed moments.
Suitable for most users and floor types
With a load capacity of 110 kg, this chair suits most users. The plastic base with standard castors is ideal for carpeted floors. Working on a hard floor such as laminate or parquet? You can optionally order hard floor castors with article number 70699952 to prevent damage to your floor.
