Adjustable backrest and Slide technology

•    The Expert 5.7 combines the ability to adjust the backrest in three positions with a sliding seat - making it easy to adjust the chair for work or rest, as well as for the user's height, which reduces pressure on the thighs and knees and promotes correct posture.



2D lumbar support

•    The adjustable lumbar support allows you to adjust the height and depth of lower back support, which reduces strain and helps maintain the natural curvature of the spine during long hours of work.



Adjustable 2D headrest

•    Height- and angle-adjustable headrest provides adequate neck and neck support, reducing muscle tension and improving comfort while working at a monitor.



3D armrests

•    Three-dimensional armrests allow you to adjust the height, tilt and front-to-back offset for a precise fit on your desk and reduce strain on your shoulders and wrists.



Pull-out footrest - quick relaxation

•    The practical footrest slides out when needed, allowing you to instantly change to a more relaxed position without having to stand up - beneficial for circulation and leg comfort.



Mesh HD fabric - breathable and durable

•    The thick weave of the Mesh HD fabric provides abrasion resistance and effective air circulation to prevent overheating and maintain comfort during prolonged sitting.



BIFMA Class 3 actuator and polyurethane-rubber casters

•    Durable gas actuator that meets BIFMA standards ensures smooth height adjustment and long mechanism life. Polyurethane-rubber blend casters move quietly and protect the floor surface.
