What does this office chair do and when do you need it?

The Topstar Sitness 90 is an ergonomic office chair specially designed for people who work long hours at a desk. With a load capacity of 110 kg, this chair offers support for a wide range of users. You need this chair if you regularly suffer from back pain or discomfort while working, or if you want to invest preventively in a healthy working posture.

Why this ergonomic variant is the right choice

This chair stands out thanks to its ergonomic contour seat with side support pads, which optimally support your pelvis and lower back. The contoured design backrest, 590 mm in height, follows the natural curve of your spine. Combined with the included armrests, you get complete support for your entire upper body while working.

Flexibility through adjustable seat height

The chair features a stepless seat height adjustment between 420 and 540 mm, so you can set the perfect seat height for your height and desk. This flexibility ensures that your feet can rest flat on the floor while your forearms rest horizontally on the desk, which is essential for an ergonomic working posture.

Optional hard floor castors for hard floors

Do you work on a hard floor such as laminate or parquet? Then you can optionally order hard floor castors (article number 70699950), specially designed to protect hard floors from scratches and to roll smoothly.
