Abstract

A stabilized ladder assembly includes a step ladder that has a set of climbing legs and a set of support legs each is hingedly coupled to a top support. A pair of lateral supports is each pivotally disposed on the step ladder. Each of the lateral supports is positionable in a deployed position to engage a support surface for inhibiting the step ladder from tipping laterally on the support surface. Each of the lateral supports is positionable in a stored position having the lateral supports resting against the step ladder. A toolbox is suspended on the step ladder such that the toolbox is accessible to a user when the user climbs the step ladder. Additionally, the toolbox is oriented to extend along a vertical axis when the step ladder is positioned in a deployed position.
