Height adjustment mechanisms are devices that allow users to change the height of furniture or equipment, such as chairs, desks, and tables. These mechanisms can be manual, like a lever or knob, or automatic, using electric motors. They are designed to accommodate different user preferences and ergonomic needs, promoting comfort and proper posture. Common types of height adjustment mechanisms include gas lift systems, which use compressed gas to raise or lower items smoothly, and scissor lift designs, which provide stability while adjusting height. These mechanisms are widely used in office furniture, medical equipment, and adjustable beds, enhancing usability and accessibility.
