What does this office chair do for you?
The Topstar Sitness 55 is an ergonomic office chair specifically designed to support your posture during long working days. With its orthopaedic seat and lumbar support, this chair helps prevent back complaints and ensures comfort while you work.

Why choose this size and this variant?
This chair offers seat dimensions of 500 x 460 mm and a seat height adjustable from 450 to 570 mm, making it suitable for people of different heights. The backrest height of 600 mm provides sufficient back support, while the included X3 armrests give extra support to your arms and shoulders.

How does the ergonomic support work?
The chair has a contoured, breathable backrest that supports your back naturally without making you sweat. The orthopaedic seat is specifically shaped to reduce pressure points, while the lumbar support maintains the natural curve of your lower back. Together, these features work to reduce fatigue and tension.

Practical considerations for use
This office chair has a load capacity of 110 kg and comes with standard castors for carpet. If you use the chair on hard floors such as laminate or tiles, you can optionally purchase hard floor castors (article number 70699950). The 100% Trevira CS upholstery is flame-retardant and durable, which is particularly important in professional environments.
