When do you need an office chair with lumbar support?
An office chair with lumbar support is essential if you sit at your desk for several hours a day. The Topstar Open Base 10 offers specific support for your lower back, which helps prevent back complaints during long working days. The mesh back design provides ventilation, so you stay comfortable even during intensive use.

Why this configuration with synchro-tilt mechanism?
The relax synchro-tilt mechanism of this chair means that the backrest and seat move together when you lean back. This keeps your feet firmly on the floor and prevents you from losing your balance. The seat height adjustment lets you adjust the seat height between 420 and 550 mm, so you can perfectly match the chair to your desk and height.

Load capacity and stability for daily use
With a load capacity of 110 kg and an aluminium base, this chair offers sturdy support for most users. The aluminium base is more durable than plastic alternatives and gives the chair a professional look. The safety double castors ensure the chair moves smoothly across different floor types without causing damage.

Practical tip for your floor type
The chair is supplied as standard with castors for carpet and soft floors. Are you working on a hard floor such as laminate or tiles? Then you can optionally order hard-floor castors (article number 70699952). These castors prevent scratches on hard surfaces and roll more softly than the standard variant.
