When should you choose a chair with a movement joint?
The Sitness 40 is ideal if you do a lot of sedentary work and want to keep your body moving while you work. The Body-Balance-Tec joint provides a subtle rocking motion that activates your core muscles and promotes blood circulation. This chair is perfect for workplaces where you concentrate for long periods, yet still want to experience the benefits of dynamic sitting.

Why choose these compact dimensions?
With a seat size of 440 x 400 mm and a seat height of 430-510 mm, this chair suits most body types. The limited seat depth of 400 mm prevents you from leaning too far back and keeps you in an active sitting position. This size works excellently in smaller office spaces where you still want a fully adjustable office chair.

The Body-Balance-Tec joint in practice
The movement joint responds to your body's motions without you having to consciously pay attention to it. You'll notice that you automatically make small adjustments to your posture, which reduces tension in the back and neck. The 100% polyester upholstery offers sufficient grip to remain comfortable while sitting through these movements.

Suitable for users up to 110 kg
The steel base supports up to 110 kg, and the backrest is adjustable between 200-300 mm in height. For hard floors, you can optionally order hard floor castors (article 70699950) to prevent scratches. Please note that for parquet or laminate you should use these special castors instead of the standard carpet castors.
