When do you need an ergonomic office chair?
A good office chair is essential if you sit behind your desk for several hours a day. The Topstar Sitness 90 is designed for people who value ergonomic seating and support for their posture while working. With its contoured seat and design backrest, this chair provides the necessary support for your back and ensures a healthy sitting posture.

Why choose this size and version?
This office chair has compact seat dimensions of 500 x 480 mm, making it suitable for most workstations without taking up too much space. The seat height is adjustable (420-540 mm), allowing you to adapt the chair to different body heights. The armrests included as standard offer extra comfort for your arms and shoulders while typing.

Load capacity and sturdiness
With a maximum load capacity of 110 kg, this chair is suitable for most users. The steel base ensures a stable foundation, while the backrest, with a height of 590 mm, provides sufficient support for your lower and mid back. The lateral support cushions in the contoured seat help keep your pelvis in the correct position.

Practical tip for different floor types
The chair is supplied as standard with castors suitable for carpet and soft floors. Are you working on a hard floor such as laminate, parquet or tiles? Then you can optionally order hard floor castors (article number 70699950). These prevent scratches on your floor and roll more smoothly over hard surfaces.
