What is ladder: Definition and 1 Discussions

A ladder is a vertical or inclined set of rungs or steps commonly used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top.

They are commonly made of metal, wood, or fiberglass, but they have been known to be made of tough plastic.
