Thanks to the Sitness hinge, this chair moves smoothly with you, so you stay comfortably seated even during long working days. The spacious shell seat with headrest and armrests offers firm support up to 110 kg.
When do you choose this product?
What is the Sitness joint and when do you need it?
This office chair is fitted with the unique Sitness joint, which provides three-dimensional movement of the seat. This dynamic seating comfort helps you stay in motion throughout your working day and offers active support. You need this if you spend long days at your desk and want a chair that moves with you.
Why choose these dimensions and load capacity?
With seat dimensions of 500 x 480 mm, this chair offers ample room for comfortable seating. The height adjustment range of 420 to 550 mm makes it suitable for most desks and body heights. The load capacity of 110 kg ensures the chair remains stable and safe, even with intensive use.
Practical comfort with Lotos faux leather
The 'Lotos' faux leather gives a professional look and is easy to keep clean. The backrest combines mesh and upholstered sections in a two-tone design, offering both ventilation and support. The backrest height of 600 mm provides good support for your back, and the included headrest and armrests complete the seating comfort.
Practical tip for different floor types
The chair is supplied as standard with castors for carpeted floors. Are you working on hard floors such as laminate, parquet or tiles? Then you can optionally order the hard floor castors (article number 70699952). These castors protect your floor from scratches and roll more smoothly over hard surfaces.
