1. A width-adjustable drop-in stair system for an in-ground vinyl liner swimming pool, comprising:
a first drop-in step component having a first length;
a second drop-in step component that is independent of the first drop-in step component, the second drop-in step component having a second length;
the first and second drop-in step components being arranged as parts of a stair step that attaches to opposing sidewall panels of the swimming pool;
the second drop-in step component is engaged in partial nested relationship with the first drop-in step component at a nesting overlap distance that is established to configure the stair step with a defined width dimension corresponding to a distance between the opposing sidewall panels at locations where the stair step is attached;
the defined width dimension being less than the first length and the second length in total; and
the first and second drop-in step components being fastened together so as to be statically secured as parts of the stair step.
