When do you need an ergonomic office chair?
This office chair is designed for people who sit at their desk for long periods every day and suffer from back problems or discomfort when sitting. The built-in lumbar support supports your lower back and prevents you from slumping. With height adjustment from 420 to 550 mm, you can adapt the chair to your height and desk height.

Why choose this Open Base 10 model?
This model combines a sturdy seat with breathable materials thanks to the mesh back and cotton upholstery (80% cotton, 20% polyurethane). The moulded seat ensures you sit stably without sinking in. With a maximum load capacity of 110 kg, this chair suits most users and offers long-lasting comfort during working days.

How does the Relax-Punkt synchronous mechanism work?
This technology ensures that the backrest and seat move in sync when you lean back. This keeps the angle between your thighs and torso optimal, which reduces pressure on your spine. The mechanism provides a natural sitting posture during various work activities, whether you lean forward to type or lean back to think.

Practical considerations for your workspace
The aluminium five-star base with safety castors is suitable as standard for soft floors such as carpet. Are you working on hard floors such as laminate or tiles? Then you can optionally order hard floor castors (article number 70699952) to prevent scratches. The height-adjustable armrests support your arms while typing.
