This office chair adapts entirely to you: the 4D armrests and synchro mechanism support a posture that feels right, while the ergonomic headrest relieves your neck during long working days. Comfortable, sturdy and ready for a load capacity of 110 kg.
When do you choose this product?
When do you need an ergonomic office chair?
This office chair is designed for people who work long days at their desk and want comfort combined with a professional look. Thanks to the synchro mechanism, the chair moves along with your body, which is essential for a healthy working posture. The ergonomic headrest supports your neck and prevents tension in your shoulders.
Why choose this Premium model?
This chair stands out thanks to its combination of different materials: a backrest with mesh fabric for optimal ventilation, sides in Softex for durability, and a seat of 65% polyester, 30% cotton and 5% viscose. The aluminium five-star base provides stability and a high-quality look in your workspace.
4D armrests for maximum comfort
The 4D armrests can be adjusted in four directions: height, width, depth and angle. This means you can fully tailor the armrests to your working posture and body height. This is especially important if you type a lot or work with a mouse, as incorrectly positioned armrests can lead to complaints.
Suitable for intensive use
With a load capacity of 110 kg and seat dimensions of 510 x 490-540 mm, this chair accommodates most users. The seat height is adjustable from 480 to 570 mm. For use on hard floors, you can optionally order special castors (article number 70699954) that prevent scratches.
