Abstract
A method for assembling a step stool includes the step of providing a frame including a front leg and a rear leg coupled to the front leg for pivotable movement between an opened use position and a collapsed storage position, a step coupled to the front leg for pivotable movement between a horizontal use position and a storage position, and a link including a body, a pivot coupled to the body and the step, and a connector coupled to the body. The method further includes the step of snapping the connector into engagement with the rear leg for movement of the rear leg from its opened use position to its closed storage position in response to movement of the step from its horizontal use position to its storage position.
