When do you choose this product?
When do you need a heavy-duty office chair?
A standard office chair is often not suitable for intensive use or higher body weights. The Big Star 20 is specially designed for heavy loads up to 150 kg and offers the stability and durability you need for comfortable, long-lasting work. This chair is ideal if you spend many hours at your desk and are looking for extra support.
Why choose this specific model?
The aluminium five-star base provides extra strength and stability, while the safety double castors ensure safe movement across different floor surfaces. The point-synchro mechanism means the backrest and seat move at the same time, supporting natural movement. With seat dimensions of 520 x 460 mm, this chair offers ample space for comfortable seating.
Extra thick padding for optimal comfort
The key feature of this chair is the extra-high padded seat, which ensures superior seating comfort during long working days. The 100% polyester upholstery is durable and easy to maintain. The 700 mm high backrest offers good support for your back.
Practical adjustment options
You can adjust the seat height steplessly between 440 and 520 mm, so you can always find the right working posture. The armrests are height-adjustable for optimal arm support. For hard floors, you can optionally order hard floor castors (article number 70699950) to protect your floor.
