What weight can the top of a lateral file cabinet safely support as a work surface?

The top surface of most commercial lateral file cabinets is rated to support 200–300 lbs of distributed load — sufficient for a printer (20–40 lbs), a small scanner, and stacked binders. However, the top is not designed as a primary work surface for active use like writing or computer work. Do not place heavy concentrated loads on unsupported spans wider than 18" and always place heavy equipment centered over the cabinet's structural corners.
