Sturdy office chair that supports up to 150 kg and keeps you comfortable for hours thanks to the extra thick seat padding. The adjustable armrests and point synchro mechanism adapt effortlessly to your working posture.
When do you choose this product?
When do you need a heavy-duty office chair?
An office chair with a 150 kg load capacity is specially designed for people who weigh more or for intensive use in professional environments. This Big Star 20 offers the sturdiness and stability needed when standard office chairs provide insufficient support. The aluminium base provides extra strength compared with plastic alternatives.
Why choose the Big Star 20 version?
This chair combines heavy-duty load capacity with professional comfort thanks to the extra-high upholstered seat. The point synchro mechanism ensures that the backrest and seat move in sync, which supports natural movement while working. With seat dimensions of 520 x 460 mm, this chair offers room for comfortable sitting throughout long working days.
Practical adjustment options
The chair features stepless seat height adjustment between 440 and 520 mm, so you can find the ideal working posture regardless of your height. The supplied armrests are height-adjustable, allowing your arms and shoulders to rest comfortably. The backrest has a height of 700 mm for adequate back support.
Suitable floors and castors
As standard, the chair is supplied with safety double castors suitable for carpeted floors. For hard floors such as laminate, parquet or tiles, you can order optional hard-floor castors (article number 70699950). This prevents damage to your floor and ensures smooth movement of the chair.
