Can flat-file cabinets be stacked to increase storage?

Yes. Flat-file cabinets are designed to be stacked — a 5-drawer unit can be placed on top of another 5-drawer unit to create a 10-drawer system. Manufacturers design the units with alignment features (notches or bolt-together connections) to keep stacked units secure. The combined unit must be placed on a stable, level floor surface. Check the total weight of the stacked configuration against floor loading capacity. OfficeFurniture2go.com sells both individual and pre-stacked flat-file configurations — call 1-800-460-0858.
