Synchronous Mechanism in Office Chairs Simply Explained

In Short

A synchronous mechanism moves the backrest and seat in a coordinated ratio, instead of remaining rigid. It is crucial that the counter-pressure can be adjusted to one's own body weight, otherwise the movement will feel too light or too heavy.

A synchronous mechanism is one of the most important functions of an ergonomic office chair. It ensures that the backrest and seat move in a coordinated manner when you lean back.

Why is this important?

Static sitting for many hours is exhausting. A good mechanism supports movement and helps to change the sitting posture more often throughout the day.

What to look for?

  • Backrest counter-pressure should be adjustable
  • Mechanism should suit body weight
  • Movement should not be too light or too heavy
  • Seat and backrest should work together harmoniously
  • Check locking and free-rocking function depending on use

Frequently Asked Questions

Does the counter-pressure strength need to be adjusted to the weight?

Yes, this is one of the most important adjustments when setting up for the first time, otherwise the chair will tilt too easily or too heavily when leaning back.

What is the benefit of locking the mechanism?

It allows the chair to be fixed in a firm position, for example, for concentrated work at the desk.

Is a synchronous mechanism equally good in every chair?

No, quality and adjustment range differ significantly between models, so testing before purchase is worthwhile.
