The present invention comprises a foldable platform step ladder having one or more railing sides which are pivotable along a first pivot axis, a first hinge which facilitates the railing sides pivoting along the first pivot axis, a platform step which is pivotable along a second pivot axis; and a second hinge which facilitates the platform step pivoting along the second pivot axis. When the railing sides or the platform step are in a use position, one of the first hinge or the second hinge are in a locked position. When the railing sides or the platform step are in a non-use position, one of the first hinge or the second hinge are in an open position allowing pivoting motion along the first pivot axis and the second pivot axis.
