Technical Specifications and Equipment
Swivel and Lift-up Mechanism: each seat comes with a swivel mechanism and a lever on the right side that allows the seat to adjust in height through a gas piston mechanism.
Adjustable Backrest: each seat backrest can be manually adjusted in height and tilted, also separately.
Permanent Contact Mechanism: the backrest can be adjusted to the desired position through the use of a lever placed under the left side of the seat. The seat comes with a central knob to adjust the tension of the backrest.
Synchronous Mechanism: it allows to adjust backrest and seat at the same time. The mechanism is activated through the lever placed under the left side of the seat: by tilting the backrest with a small pressure, the seat slides backwards and slightly lowers down; this mechanism has a lock system to block the position. The seat also has a central valve to adjust the backrest tension quicker.
Safety Antishock System: each seat with Permanent Contact or Synchro Mechanism is equipped with an Antishock mechanism that prevents the backrest to immediately go back to the vertical position once released. To move the backrest simply apply a light backward pressure with the back; In this way it will be released and will follow the user back movement to regain the vertical position.
Lumbar Support: in black polypropylene, it is easily adjustable in height thanks to two small levers that will make it slide inside the back mesh and thanks to a snap mechanism that locks it in position.
Flexible Headrest: made of black polyurethane.

Optional
armrests also adjustable in width: available for seat with height adjustable armrests.
armrests also adjustable in width and depth: available for seat with height adjustable armrests; the depth regulation also allows to move the armrests.
seat adjustable in depth: device that allows the seat depth to be adjusted, only available with the synchro mechanism. The seat slides forwards and backwards by activating a lever placed below the right side of the seat. The movement is allowed only when the synchro mechanism is blocked.
