Sturdy office chair that moves with you thanks to the point synchro mechanism and supports up to 150 kg. The extra thickly upholstered seat and adjustable armrests ensure comfortable sitting, even during long working days.
When do you choose this product?
When do you need a heavy-duty office chair?
The Topstar Big Star 10 is specially developed for intensive use and offers support for users with a load capacity of up to 150 kg. This office chair is the ideal choice when you need a robust workstation that can withstand daily, prolonged use. The extra high-padded seat ensures comfort during long working days.
Why these dimensions are optimal
With seat dimensions of 520 x 460 mm, this chair offers sufficient space for comfortable sitting. The seat height is infinitely adjustable between 440 and 520 mm, so you can adapt the chair precisely to your height and desk proportions. The backrest height of 600 mm provides good support for your back.
How the point-synchro mechanism works
The point-synchro mechanism ensures that the backrest and seat move in proportion to each other when you lean back. This mechanism supports a natural sitting posture and reduces the strain on your spine while you work. The adjustable armrests type 'TW1' can be adjusted in height for optimal arm support.
Practical tip for different floor types
The chair comes as standard with safety double castors suitable for soft floors such as carpet. For use on hard floors such as laminate or parquet, you can optionally order hard floor castors with article number 70699950. The aluminium base offers stable support and has a long lifespan.
