3. Not all office chairs feature a traditional four-legged design. Some are designed with mounted wheels, known as casters, that allow you to roll around and rotate while sitting in them. If you have an L-shaped desk, for example, you can roll or rotate between the different areas of your desk. If you have a computer on one area of your desk and a writing station on the other area, you can quickly move between these areas without standing up if you choose an office chair with casters.
On its website, the Occupational Safety and Health Administration (OSHA) recommends the use of office chairs with five casters in computer workstations to promote productivity and reduce the risk of injury. You can still use traditional four-legged chairs in conference rooms, waiting rooms and breakrooms. For computer workstations, though, choosing a five-wheeled office chair will improve your productivity while creating a safer workplace in the process.
