What does this office chair do?
The Topstar Sitness 90 is an ergonomic office chair that supports you during long working days at your desk. Thanks to the ergonomic contour seat with side support cushions, you get optimal support for your body. The chair helps you adopt a healthy working posture and reduces fatigue.

Why choose this size?
With seat dimensions of 500 x 480 mm, this chair offers enough room for comfortable seating without taking up too much space. The height-adjustable seat (420-540 mm) ensures you can find the perfect seat height for your desk and body height. The load capacity of 110 kg makes it suitable for most users.

Ergonomic support where it matters
The contoured design backrest with a height of 590 mm effectively supports your back. The side support cushions in the seat provide extra stability and comfort while you work. The steel base ensures a sturdy foundation and durability, while the supplied armrests relieve your arms and shoulders.

Practical tip for your floor
The chair is fitted with load-dependent braked safety double castors for carpeted floors. Are you working on a hard floor such as laminate or parquet? Then you can optionally order hard floor castors (article number 70699950), which protect your floor from scratches and ensure smoother movement.
