When do you choose this product?
When do you need an ergonomic office swivel chair?
An office swivel chair with ergonomic features is essential if you spend hours a day at a desk. The Sitness Airwork is specifically designed for people who do a lot of computer work and want to improve their posture while sitting. The combination of dynamic sitting and back support helps you prevent stiffness and boosts your productivity.
Why choose this specific model?
This chair stands out thanks to its three-dimensionally moving special flat seat, which keeps your body automatically active while you work. The mesh back with adjustable lumbar support ensures optimal air circulation and back support. With a load capacity of 110 kg, this model suits most users, while the synchronous mechanism provides natural movement between the seat and backrest.
Flexible height adjustment
The infinitely adjustable seat height of 450 to 570 mm makes this chair suitable for different body heights and desk heights. The seat dimensions of 455 x 410-475 mm offer plenty of room without being too bulky. This flexibility means you can always adopt the right working posture, regardless of your height.
Practical considerations for your workspace
The chair comes standard with armrests and castors for carpet. Do you work on a hard floor? You can optionally order hard-floor castors (article number 70699952) for better protection of your floor. The black plastic base fits in almost any office setting and requires little maintenance.
