When should you choose an ergonomic office chair?
This office chair is essential when you work at a desk for long periods and want to combine comfort with good support. The multifunctional headrest and mesh back ensure that your neck and back stay in the right position, while the synchro-relax mechanism follows your movements naturally. This prevents fatigue and tension complaints during long working days.

Why these dimensions suit your workspace
With seat dimensions of 480 x 500 mm and an adjustable height of 430 to 520 mm, this chair fits most standard desks and users. The backrest height of 550 mm provides sufficient back support for people of average height. The 110 kg load capacity makes the chair suitable for a wide range of users.

Benefits of the synchro-relax mechanism
The synchro-relax mechanism is the core of this office chair and ensures that the seat and backrest move in sync when you lean back. This mechanism supports your natural movements and keeps your body in balance. The combination with the mesh back provides good ventilation, so you stay comfortable even in warm weather.

Practical tip for different floor types
The chair comes as standard with castors suitable for soft floors such as carpet. Are you working on a hard floor such as laminate or tiles? Then you can order optional hard-floor castors (article number 70699952). These castors protect your floor against scratches and allow the chair to move more smoothly.
