Office chairs have variety of mechanisms and adjustments that are often not used because their function and existence are unknown. They are very useful mechanisms to have a correct posture and prevent any skeletal muscle pain that can arise while sitting 8 hours a day.
Below we have prepared a small guide to the various mechanisms that can be found in a session:
OSCILLATING MECHANISM (TILT MECH)
SYNCHRO MECH MECHANISMThe synchro mechanism allows the seat and backrest angle to be adjusted synchronously, according to a ratio of 1:2.5, i.e. each degree of greater (or lesser) seat tilting corresponds to 2/2.5 degrees of greater (or lesser) backrest tilting.
ASYNCHRO MECHANISM (ASYNCHRO MECH)The asynchronous mechanism allows independent adjustment of the backrest and seat inclinations. The asynchro allows to find the optimal static position of the office seating, which varies from person to person, even if it has no oscillation, i.e. it does not allow to reach a dynamic position, such as the synchro mechanism.
