What does this office chair do for your working comfort?
The Topstar Sitness 90 is designed for daily office work where you sit for hours at a time. This ergonomic office chair supports your body by following the natural shape of your back and provides stability while typing, calling or attending meetings. You can adjust the seat height steplessly to find the perfect working position.

Why choose this specific size?
With seat dimensions of 500 x 480 mm, this chair offers enough space for most users without taking up too much room. The seat height is adjustable from 420 to 540 mm, so you can match the chair precisely to your desk and body height. The 590 mm high backrest provides support for your lower and middle back.

How does the ergonomic design work?
The contoured seat design moulds to your body, while the side support cushions ensure you don't sink too far in. The design backrest follows the natural curve of your spine. The chair is made of 100% polyester upholstery and has a sturdy steel base that is resistant to intensive use.

Practical considerations for daily use
