Sturdy office chair that can handle up to 150 kg yet stays comfortable thanks to the extra thickly padded seat. Conveniently adjustable armrests and an aluminium base provide stability during long working days.
When do you choose this product?
When do you need a heavy-duty office chair?
This office chair is specially designed for people who need more support than a standard office chair can provide. With a maximum load of 150 kg, the Big Star 30 offers the stability and durability you need for long hours of sitting. The extra thickly padded seat ensures greater comfort during long working days.
Why choose this specific version?
This blue variant combines functionality with a striking colour that brings atmosphere to your workspace. The 100% polyester upholstery is easy to maintain and hard-wearing. The aluminium base contributes to the chair's sturdiness and can easily support the higher weight.
How does the advanced mechanism work?
The point synchronous mechanism ensures that the backrest and seat move in proportion to each other when you lean back. You can adjust the seat height steplessly between 440 and 520 mm, so you can always adopt the right working posture. The armrests are height-adjustable for optimal arm support.
Practical considerations for your workspace
The chair comes as standard with safety double castors suitable for carpets and soft floors. Do you have a hard floor such as laminate or tiles? Then you can optionally order hard floor castors (article number 70699950) for optimal protection of your floor and smooth movement.
