Teles Office Chair Adjustment
"Teles" may be a misspelling of "Stressless". Currently, no publicly available information on the specific adjustment methods for office chairs of this brand has been retrieved, but the following are common adjustment methods for office chairs:

Pneumatic Rod Adjustment
Pneumatic rod adjustment is a relatively common method. When using it, first sit steadily on the chair and lean your body slightly forward. Then, find the pneumatic rod control lever under the chair. If you want the chair back to tilt backward to adjust the front-back angle, simply pull the control lever upward while gently leaning back, and the chair back will tilt backward according to your needs. When you need the chair to return to its original position, push the control lever downward and lean your body forward, and the chair will slowly return to its initial state. During the operation, try to be as slow as possible to avoid losing balance or damaging the chair due to excessive movement.
Knob Adjustment
The knob adjustment usually places the adjustment knob on the side or bottom of the chair. When you need to adjust the backrest angle, rotate the knob counterclockwise. At this time, the backrest lock will be released, and you can freely adjust the front-back tilt angle of the backrest according to your own needs. After adjusting to the appropriate position, rotate the knob clockwise to fix the backrest at the current angle. During the adjustment process, do not use excessive force to avoid damaging the knob or affecting the normal use of the chair.
Lever Adjustment
Some high-end office chairs are equipped with a lever adjustment device, which is usually located on the side of the chair. Pulling the lever can switch between different gears, and each gear corresponds to a fixed front-back tilt angle of the backrest. You can choose the appropriate gear according to your sitting comfort to obtain the most comfortable sitting experience.
Tilt Tension Knob
The tilt tension knob is mostly placed under or at the back of the seat. By rotating this knob, you can adjust the resistance of the chair back when leaning backward. If you rotate the knob clockwise, it will increase the resistance of the chair back when leaning backward, making the chair back more stable, which is suitable for scenarios where you need to maintain a relatively upright sitting posture. If you rotate the knob counterclockwise, it will reduce the resistance, making leaning backward easier, which is suitable for use during rest. Some models of office chairs are also equipped with a tilt lock lever, which can fix the chair back at a specific angle to meet different usage needs.
