A ladder assembly having a front frame having a first pair of spatially disposed legs, a plurality of rungs extending between the first pair of legs, and a pivot bracket mounted at the top of the front frame, a rear frame having a second pair of spatially disposed legs, one or more rungs extending between the second pair of legs, and a fixed bracket mounted at the top of the rear frame, wherein the pivot bracket is attached to the fixed bracket via a single point pivot bracket system configured to pivotally connect the front frame and the rear frame, a folding bracket system configured to keep a correct angle between the front frame and the rear frame, thereby allowing the rotational movement of the legs.
