How many sections can flat file cabinets be stacked safely?

Most flat file cabinet systems are designed to stack 2–3 sections safely — always check the manufacturer's specifications. Two 5-drawer sections stacked gives you a 10-drawer cabinet at a comfortable working height (typically 36"–40" total). Three sections (15 drawers) start to get very tall and require secure wall anchoring to prevent tipping. Beyond three sections, most manufacturers don't recommend stacking because the center of gravity becomes high relative to the base footprint. Always anchor stacked sections to the wall.
