When do you need an ergonomic office chair?
This Topstar Sitness 55 is designed for people who work at a desk for long periods every day and suffer from back complaints or want to prevent them. The chair provides support for your lumbar spine and has an adjustable seat height, allowing you to adopt a healthy working posture. Thanks to the ergonomic design, you help reduce tension in your back, neck and shoulders.

Why choose these compact dimensions?
With seat dimensions of 500 x 460 mm and a seat height adjustable between 450 and 570 mm, this chair suits a range of body heights and office layouts. The load capacity of 110 kg makes it suitable for most users. The steel base ensures stability, even during intensive use.

What makes the Orthositz special?
Topstar's Orthositz technology combines a contoured, breathable backrest of 600 mm height with specific lumbar support. The 100% Trevira CS upholstery is flame-retardant and durable. You get support where you need it, without the chair becoming too warm during long working days.

Practical considerations for installation
The chair is delivered with X3-type armrests that provide extra comfort for your arms and shoulders. If you use the chair on a hard floor, you can optionally purchase hard floor castors (article 70699950) to protect your floor and improve rolling behaviour. Check whether your current castors are suitable for your floor type.
