What’s the best time to replace an old office chair?

Have you got an aging office chair to sit at your desk in? Chances are your old chair is rather shabby looking with casters that rolled fine when new but are now quite dodgy and likely to collapse sending you tumbling onto the floor at any time. If you have been putting off buying a new chair for ages to save money, don’t wait any longer. New ergonomically designed office chairs can be had at very reasonable prices and the investment is worth it too when you consider how much productivity is lost to an old chair that doesn’t support you, causing back pain and necessitating extra breaks to unkink your whole body.
