To adjust the seat height, locate the lever on the right side beneath the seat. Pull the lever upwards while seated to lower the seat, or pull the lever upwards while standing to raise the seat. Release the lever at your desired height. The SGS-certified gas cylinder allows for a 3.9-inch adjustment range, accommodating users from approximately 5.3ft to 6.5ft.
