This office chair moves with you thanks to the synchro mechanism and three-dimensional seat, so you stay comfortable for hours. The adjustable lordosis support supports your lower back exactly where needed.
When do you choose this product?
When do you need an office chair with a mesh back?
The Sitness Airwork is designed for people who spend a lot of time sitting down and need good ventilation and back support. The mesh back ensures air circulation, which is especially pleasant during long working days or in warmer environments. This chair is suitable for intensive daily use in the office or home office.
Why choose this size and load capacity?
With a seat width of 455 mm and a seat depth of 410-475 mm, this chair offers comfortable space for most users. The load capacity of 110 kg makes it suitable for a wide range of people. The seat height is adjustable from 450 to 570 mm, so you can adapt the chair to different body heights and desk heights.
How does the special seat work?
What makes this chair special is the three-dimensionally movable flat seat that adapts to your body movements. Combined with the synchro mechanism, the seat moves with you when you lean back, which promotes a natural sitting posture. The mesh back has a height of 575 mm and features an adjustable lumbar support for optimal support of your lower back.
Practical consideration regarding the floor surface
The chair is supplied as standard with castors suitable for carpet and soft floors. Are you working on a hard floor such as laminate or tiles? Then you can optionally order the hard floor castors (article number 70699952). These protect your floor against scratches and roll more smoothly over hard surfaces.
