What does this product do?
This swivel office chair is designed for everyday office work where you spend a lot of time sitting down. The synchro mechanism ensures that the backrest and seat move together, which supports a natural sitting posture. You can use the chair for a variety of tasks where comfort and support are important.

Why this specific synchro mechanism?
The synchro mechanism sets this chair apart from simple swivel chairs with height adjustment only. When you lean back, the seat tilts along slightly, keeping your pelvis in a better position and your spine maintaining its natural curve. This mechanism is especially valuable if you regularly switch between different tasks.

Breathable backrest with lumbar support
The backrest has a mesh covering that allows air circulation, which is pleasant during longer work sessions. The integrated lumbar support provides specific support for your lower back. With a backrest height of 620 mm, the backrest reaches roughly shoulder-blade height for most users.

Practical details for daily use
The chair has a seat width of 480 mm and a seat depth of 440 mm, suitable for most body types. You can adjust the seat height steplessly between 430 and 540 mm. With a load capacity of 110 kg, the chair is sturdy enough for intensive use. If you use the chair on hard floors, you can order optional hard floor casters (article number 70699950) to prevent scratches.
