Many businesses wonder if it’s a good idea to stack filing cabinets, but it can depend on a number of different factors. One of the most critical things to consider is the size of the metal filing cabinet. You can manage it with smaller units, but larger ones should never be stacked. You also want to avoid storing any heavy or bulky items on the top file cabinet. Doing so could make them top-heavy, which could cause them to fall. It’s better to store them in the bottom drawer of the bottom cabinet if you can.
