Here are a few technical terms to help you choose the right office chair.
The seat height is adjustable by means of a gas-operated jack (this adjustment is of course also available on all the other mechanics shown below).
The backrest follows your movements and remains in constant contact with your back. It can also be locked in your chosen position. The seat, on the other hand, remains fixed, so there’s no adjustment for tilt.
Example of Sitek models in permanent contact:

The backrest and seat move at the same time and tilt in a ratio that always offers optimum comfort. The backrest return force can be adjusted to suit your body shape and weight (tension adjustment).
An anti-return safety system prevents the backrest from returning on its own when the mechanism is released. You need to press your back against the backrest to release the backrest position.

The most ergonomic solution
Same as the synchronous system, but with an additional system for the seat. The seat depth can be adjusted over a range of around 6 cm. This allows the seat to be adapted to the size of the user’s legs.
Example of Sitek synchronous models with seat translation :

These mechanisms are generally found on leather or fabric executive or chairman chairs.
Centered tilting:
The seat tilts back and forth for relaxation. Tension can be customized to suit the user’s morphology.
Example of Sitek centered tilt models:

Off-center tilting:
With an off-center mechanism, the seat’s axis of rotation is moved forward, while the feet remain in contact with the floor. The result is a more natural, smoother tilting action. Tension can also be customized to suit the user’s morphology.
Example of off-center tilting Sitek models:

Some options:
– Armrests: reduce fatigue in the shoulders, vertebrae and cervical vertebrae by taking the strain off the arms. They also reduce the risk of musculoskeletal disorders.
– Hard floor castors: for tiled and concrete floors. The castor is made of a highly resistant material and covered with a shock-absorbing rubber tread.
We hope you find these tips on “Choosing the right office chair” useful.
