Description
Additional information

Mechanism

The 4U chairs are equipped with a synchronous SP5 mechanism, which allows the backrest to recline simultaneously with the seat (the backrest moves faster and further), while also providing the option to lock the backrest in the standard work position (0°). The SP5 mechanism also enables seat depth adjustment and seat height adjustment via a pneumatic lift. Additionally, the chair includes an Anti-Shock function, preventing the backrest from suddenly striking the user after the lock is released.

Backrest

Made from breathable mesh, ensuring proper ventilation and comfort even during extended periods of use.

Lumbar Support

The backrest features an adjustable lumbar profile that can be customized for both height and depth, offering tailored support for the lower back.

Seat

Upholstered with the selected fabric and filled with foam of 64 kg/m³ density, the seat guarantees comfort and durability. The chair also includes a seat depth adjustment function, allowing the user to customize it to their individual needs.

Armrests

The R12 armrests are adjustable in four dimensions (height, forward-backward, distance from the seat, and angle of the armrest pad), offering full flexibility to find the most comfortable position.

Base

Available in two versions—polished aluminum or black nylon. The base is equipped with soft 60 mm diameter wheels, which are gentle on flooring.
