The American Society for Testing and Materials (ASTM) has established standards for manufacturers which stipulate that dressers, chests of drawers and armoires should be able to remain upright when any doors or all drawers are open two-thirds of the way, or when one drawer or door is opened and 50 pounds of weight are applied to the front, simulating a climbing child. In addition, Underwriters Laboratories (UL) requires units to be able to remain upright when placed on a 10-degree angle with 70 pounds on top, to simulate the weight of a television. The ASTM and UL standards are voluntary, however, and many manufacturers will cut corners to save money. And despite efforts by the CPSC to enforce these standards, sub-standard furniture is still regularly sold at retail stores.
