3. Operating Instructions
Your amseatec LY-5192 Office Chair offers several adjustable features to customize your seating experience for maximum comfort and support.
Adjustable Features
- Height Adjustment: Use the lever located under the seat on the right side to adjust the chair's height. To raise, lift the lever while taking your weight off the seat. To lower, lift the lever while seated.
