Abstract
A ladder that would have a plurality of legs that would be independently adjustable from each other is disclosed. Each leg would have an incorporated adjustable leg that could be set at a varying height, with each adjustable leg having a non-skid pad on the bottom to minimize the risk that the ladder would slip when in use.
