Operating Instructions
The Kensaker Executive Leather Office Chair KLBY619 offers several adjustable features to customize your seating experience for optimal comfort and ergonomic support.
Adjustable Functions:
- Seat Height Adjustment: Use the lever located under the seat on the right side to raise or lower the chair. To raise, lift the lever while standing; to lower, lift the lever while seated.
- Backrest Tilt and Lock: The chair's backrest can be tilted between 90° and 135°. Use the lever on the left side to unlock the tilt function, allowing the backrest to recline. Push the lever back in to lock the backrest at your desired angle.
- Tilt Tension Adjustment: A knob under the seat allows you to adjust the tension of the tilt mechanism. Turn clockwise to increase tension (for heavier users or less recline) and counter-clockwise to decrease tension (for lighter users or more recline).
- Adjustable Headrest: The headrest can be adjusted vertically by pulling it up or pushing it down to align with your neck and head for personalized support.
- Reversible Armrests: The armrests can be flipped up and out of the way, providing flexibility for different tasks or to allow the chair to be pushed closer to a desk.
