Office chairs with multiblock mechanism

Multiblock

— this type of mechanism provides the ability to rock back and forth, change the rocking stiffness, and also fix the tilt of the chair in four different positions. The back and seat are rigidly connected. Also, such models are often equipped with an “anti-shock” system: when the latch is removed, the chair does not change its inclination until the user pulls it in the right direction. This avoids jerks and bumps.
