Height adjustment refers to the ability to change the vertical position of an object, such as a chair, desk, or equipment. This feature is commonly found in ergonomic furniture, allowing users to customize their workspace for comfort and efficiency. By adjusting the height, individuals can maintain proper posture and reduce strain during activities like typing or studying. Many modern office chairs and desks come with mechanisms for height adjustment, including pneumatic levers or manual screws. This adaptability is essential for accommodating different body types and preferences, promoting a healthier work environment and enhancing productivity.
