Operating Instructions
Your Kensaker Executive Leather Office Chair offers several adjustable features for personalized comfort:
- Height Adjustment: Locate the lever under the seat on the right side. Pull the lever up while seated to lower the chair, or pull it up while standing to raise the chair. Release the lever to lock the height.
- Tilt Function: The chair features a 90-135° tilt. Pull the lever under the seat (usually on the left side) outwards to unlock the tilt mechanism, allowing the chair to recline. Push the lever inwards to lock the backrest in your desired position.
- Tilt Tension Adjustment: The round knob under the front of the seat controls the tension of the tilt mechanism. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).
- Adjustable Headrest: The headrest can be adjusted vertically to provide optimal neck support. Gently pull or push the headrest to your preferred height.
- Flip-Up Armrests: The armrests can be flipped up to allow the chair to be pushed closer to a desk or for easier entry/exit. Lift the armrests upwards until they lock into the vertical position. Push them down to return to the horizontal position.

Maintenance
To maintain the quality and appearance of your Kensaker office chair:
- Cleaning: Wipe clean with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners, as these can damage the PU leather.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the leather to fade or crack.
