Expert 7.9 ergonomic chair

Created for intensive sitting

•    Expert 7.9 is an armchair designed for people who spend long hours at a desk - both for work and entertainment. The large adjustment range allows you to tailor the chair to your individual needs, which translates into greater comfort and less fatigue during long sessions.

Precise adjustment

•    Adjustable backrest height, seat depth and features such as SeatRest and Slide make it possible to set the chair perfectly to your body shape and work mode - from concentrated work to relaxation.



For home and office - active sitting

•    A static position can put a strain on the spine - that's why the Expert 7.9 is equipped with mechanisms that allow you to actively change your position while working. The ability to adjust the seat depth and backrest tilt helps reduce muscle tension and fatigue.

Adjustable backrest height

•    The Multilock mechanism with three levels of backrest height allows you to precisely adjust its position to the user's height, improving the ergonomics of sitting.



5D armrests
360° rotation

•    Advanced adjustment of the armrests allows you to adjust their height, angle and position, and the ability to fully rotate gives you freedom of positioning regardless of your sitting position.



Ventilated and durable fabric

•    Mesh HD fabric with a coarse weave combines durability with high air permeability, which increases seating comfort especially on hot days.
