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 an ergonomic sitting posture thanks to the special orthopaedic seat construction and supports your body during intensive working days.

Why choose these compact dimensions?
With seat dimensions of 500 x 460 mm and an adjustable seat height of 450 to 570 mm, this chair fits well in smaller workspaces without compromising on comfort. The 600 mm high backrest offers sufficient support for your back without being too bulky for more compact office layouts.

What makes the lumbar support special?
The integrated lumbar support specifically supports the natural curve of your lower back. Combined with the contoured, breathable backrest, your back stays comfortable even on warm days, and you get the right support exactly where you need it most.
