An adjustable desk is a type of furniture that allows users to change the height of the work surface. This feature enables individuals to switch between sitting and standing positions, promoting better posture and reducing the risk of discomfort during long hours of work. Many adjustable desks are powered by electric motors, while others use a manual crank or lever system. These desks are popular in both home and office settings, as they cater to various user preferences and needs. By accommodating different heights, an adjustable desk can enhance productivity and overall well-being, making it a valuable addition to any workspace.
