The gas lift system allows for easy and precise height adjustment. This is crucial as it enables users to customize the chair's height according to their desk height and personal preferences. By simply pulling up or pushing down on the lever, the seat can be raised or lowered smoothly within a specific range. For example, a typical gas lift chair might have a height adjustment range from about 16 inches to 20 inches from the floor to the top of the seat, ensuring a proper fit for different body sizes and workstation setups.
