When do you need an ergonomic office chair?
A good office chair is essential if you sit at your desk for several hours a day. This Topstar Sitness Open X combines comfort with movement thanks to the integrated Sitness joint in the seat, which promotes active sitting and better blood circulation during long working days.

Why choose this specific model?
The combination of breathable mesh upholstery on the backrest and a comfortable saddle seat makes this model suitable for anyone who values ventilation and support. With a seat height that is infinitely adjustable between 450 and 550 mm, this chair suits different body heights and desks.

What does the Punktsynchron mechanism offer?
The Punktsynchron mechanism ensures that the backrest and seat move in proportion when you lean back. This supports your natural movement and keeps your spine in a healthy position. The maximum load of 110 kg indicates that the chair is suitable for most users.

Practical considerations for your workspace
The seat dimensions of 470 x 470 mm provide enough room without taking up too much space. Please note that if you use the chair on hard floors, you can purchase optional hard floor castors (article 70699954) to protect your floor. The supplied armrests support your arms and shoulders while typing.
