Seat Height

Harmonic™ Tilt Tension

Tab next to tilt tension knob, lower right

To raise: While taking your weight off chair, lift tab up.
To lower: While sealed, lift tab up.

Adjust chair height so your feet rest flat on the floor or footrest, with your body comfortably supported by breathable AireWeave™ suspension. Avoid dangling legs, which puts pressure on the back of thighs and restricts blood flow. A work surface or keyboard that seems too high or low may require adjusting.

For maximum back support, adjust chair depth (distance from hip to knee) so the seat edge doesn’t hit the back of your legs.

Forward Tilt

Tilt Limiter

Horizontal tab on left front
side of seat

To position chair forward: Recline and flip lever down.
To resume horizontal position: Recline and flip lever up.

Forward tilt with a 4-degree range provides full support while leaning forward for task-intensive work, such as keyboarding. Normally, forward tilt position is used with increased chair height. This position helps the body achieve a more neutral, open angle between trunk and thighs.

Vertical tab on left front side
of seat

To engage: Recline and move lever up to define the limit of recline.
To release: Lean forward and press lever back.

If you want to sit in an upright position, set the tilt limiter when the seat is in a horizontal or forward position.

Lumbar Height

Lumbar Depth

Levers on lumbar support

To raise or lower: Move levers up to loosen, slide lumbar support up or down to desired height.

Although the chair back automatically adjusts to your size and posture, you can fine-tune lumbar support by adjusting the bar so that it comfortably supports the natural curve of your spine. Once support is adjusted, it follows you throughout your range of recline.
