Ladder

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 flexible ladders, such as those made of rope or wire rope, that may be hung from the top.
