When should you choose an ergonomic office chair?
An ergonomic office chair such as the Sitness 55 is essential if you sit behind your desk for several hours a day. The ergonomic orthopaedic seat promotes a healthy posture while you work. With the seat height adjustable between 450 and 570 mm, this chair suits different desk heights and body types.

Why choose these specific dimensions?
The seat dimensions of 500 x 460 mm provide a comfortable seating surface for most users. The backrest height of 600 mm gives sufficient support to your upper body without restricting movement. The maximum load of 110 kg makes this chair suitable for a wide range of users.

Benefits of the lumbar support and ventilation
The built-in lumbar support supports your lower back and helps prevent back complaints. The contoured, breathable backrest ensures your back doesn't get sweaty during long working days. This combination of support and ventilation keeps you comfortable and productive.

Practical considerations when using the chair
The supplied X3 armrests provide extra support for your arms and shoulders. The steel five-star base ensures stability on carpets and soft floors. For hard floors, you can optionally order hard floor castors (article number 70699950) to protect your floor and move smoothly.
