Raise or lower to support the lumbar (lower back) region of your spine. The back height adjustment operates on a ratchet system and the backrest can be set in any one of 4 positions.
Allows you to raise or lower the seat height on your Ergohuman chair so your feet rest flat on the floor. When correctly adjusted your upper legs should be angled slightly downwards.
This feature allows you to change the depth of the seat to accommodate the length of your legs. When correctly adjusted, you should be able to place your clenched fist between the edge of the seat and the back of your knee. This will keep your back in contact with the backrest while avoiding pressure behind your knees.
The headrest can be tilted and height adjusted to individually suit the user’s requirements.
Adjust to change the angle of the back in relation to the seat. Will allow for multiple angles based on the individual’s requirements. The seat back can be locked in any one of 3 positions, or operated in free-float mode to follow the user’s movement.
Raise, lower, angle and depth adjust the armrests so your forearms rest comfortably while sitting at a desk.
