Push the backrest angle adjustment lever completely foward and lean against the back until desired angle is achieved, and then return the lever to the original position to lock. There are 4 positions with 25° range.
Backrest angle can reduce pressure on the spine.
Pull lever outward, open the tilt tension adjustment handle and turn handle foward or backward for desired tension. Or, pull lever outward, leave handle closed and turn lever foward or backward for slight tension adjustment. Push lever inward to original position to lock tilt after adjusting.
The synchro mechanism is ergonomically designed to enhance comfort and reduce strain. The back-to-seat adjustment/tilt is 3:1 ratio.
While sitting on the chair, press the backrest height adjustment buttons to change the height of backrest.
Press the buttons on the outside of the armrests to raise or lower to desired height. There are 8 positions with 3.15" range.
Recommended armrest position: Allow arms to rest comfortably on the armrests at a 90° angle while the armrest is 1" higher thean the elbow.
Arm pads swivel to three pre-set positions. Each position is achieved by moving the arm pads outward or inward.
The best angle is when the arms can rest naturally on the arm pads while working.
Push the arm pads outward or inward to the desired width. There isa 1.57" range of arm pad width adjustment.
Push the arm pads forward or backward to a desired depth. There is a 1.38" range of arm pad depth adjustment.
Push the seat height adjustment lever backward and hold it while raising or lowering the seat to change the seat height. When the lever is released, the seat height is locked.
An incorrect seat height contributes to back fatigue, it is recommended that the angle of knees is slightly less than 90° and feet are level with the floor.
Move the seat depth adjustment pull out to adjust the seat depth (aprox range of 1.97"). When the pull is released, the position will be locked.
Ideal depth is achieved when the upper legs are on the seat, the lumbar area is in contact with the back of the chair, and the back of knee does not touch the edge of seat.
