5. Operating Instructions
Your Waleaf Executive Office Chair offers several adjustable features for personalized comfort.
5.1. Height Adjustment
To adjust the chair height, locate the lever on the right side, beneath the seat. While seated, pull the lever up to lower the chair. To raise the chair, stand up slightly and pull the lever up. Release the lever at your desired height.
5.2. Lumbar Support Adjustment
The chair features an adjustable ergonomic lumbar support. Rotate the lumbar support knob, typically located on the side of the backrest or beneath the seat, to modify the level of support to fit your lower back curve.

The backrest angle can be adjusted between 90° and 120°. Use the rocking control knob, usually located on the underside of the seat, to set your preferred tilt resistance. Pull the lever (often the same as the height adjustment lever) outwards to unlock the tilt function, allowing the chair to recline. Push the lever inwards to lock the chair in an upright or reclined position.
