Conceived to meet the highest demands in terms of comfort and occupational health, Aktiva is a chair that meets all your expectations. It is designed to promote dynamic user postures and avoid muscle injuries.
It has a backrest flexion system based on a metal frame that is unique in its category, since it allows the lateral flexion of the backrest without losing the security provided by a rigid support.

The seat is made of injected polyurethane foam with an anatomical shape, forcing the user to sit correctly and promoting blood circulation in the legs.
It has height-adjustable lumbar support and there is the possibility of incorporating an upholstered headrest, adjustable in height and angle.
The backrest is also made of injected polyurethane foam and designed for breathability. Forced ventilation channels direct air to a rear outlet integrated into the back shell, improving biothermal comfort.
It incorporates an advanced synchronized mechanism, with lateral tilt tension adjustment. In addition, its articulated quadrilateral system allows the seat to tilt with respect to a virtual axis of rotation located at the knees. This keeps the distance from the knees to the floor constant.
On the other hand, it allows the two backrest tubes to move independently, providing extra mobility.

Thanks to its innovative flexible backrest, lumbar support becomes more prominent as the user leans forward. The backrest curves at the bottom (increasing the X-axis distance), adapting to the natural curve of the spine.
Furthermore, it can flex and rotate at the top, allowing the user to twist their back without losing contact with the backrest.


BLACK
Includes a 5-spoke base made of polyamide. The rear frame features an elegant matte black finish, providing a sober and professional aesthetic.
CHROMED
Incorporates a polished aluminum base. The rear frame has a chromed finish, providing a more sophisticated and high-quality look.
COLOR
Equipped with a painted aluminum base, available in the 7 colors of the range. The rear frame is painted in the same color as the base, achieving a uniform and contemporary image.
