This sturdy office chair offers extra comfort thanks to its high-padded seat and supports up to 150 kg. With adjustable armrests and point synchro mechanism, you can easily adjust it to your working posture.
When do you choose this product?
When do you need a heavy-duty office chair?
A heavy-duty office chair such as the Big Star 30 is designed for users who need more support than standard office chairs provide. With a load capacity of 150 kg, this chair is suitable for people who sit for long periods and require reliable stability. The extra high-padded seat provides lasting comfort during long working days.
Why choose this robust version?
The aluminium five-star base and safety double castors make this chair particularly stable and durable. The seat dimensions of 520 x 460 mm offer ample room for comfortable sitting, while the backrest height of 800 mm provides good back support. This combination makes the chair suitable for intensive daily use.
How does the point-synchronous mechanism work?
The point-synchronous mechanism ensures that the seat and backrest move in sync when you lean back. This supports a natural sitting posture and reduces fatigue. The chair features a infinitely adjustable seat height between 440 and 520 mm, so you can find the ideal working position regardless of your height.
Practical tip for different floor types
The supplied safety double castors are suitable for carpeted floors. Are you working on a hard floor such as laminate or parquet? Then you can optionally order hard floor castors with article number 70699950. The height-adjustable 'TW1' armrests complete the ergonomic support for your arms and shoulders.
