A ladder is a device that allows vertical access from a higher level to a lower level – or vice versa. It is usually inclined at an angle but can be vertical if adequately fixed to a wall.

A ladder typically comprises two uprights that are connected by a series of parallel horizontal elements called 'rungs' which support a person’s weight and can be thought of as steps: stepping on one rung after another produces vertical movement either to allow ascent or descent.

== Ladders may be differentiated by: ==

* Telescoping ladder (usually aluminium) – these are relatively recent products made of tubular aluminium. They can have a reach of 3-4m and the vertical sections and rungs telescope into a very compact package around 1m-high which can be easily carried and is more suited to domestic use.
* Cat ladder: usually a steel or aluminium ladder that features a protective cradle along all or some of its extent. Users are therefore afforded some protection from falling while moving within the cradle. Cat ladders are usually permanent fixtures bolted to the outside of buildings.

* Wood ladders are usually the simplest of all and are the traditional solution. Unlike steel or aluminium, they usually have a limited vertical reach and are less durable. The wood – with time – may become weakened or the rungs may be damaged and therefore become dangerous. They are also easier to vandalise as wooden rungs can be sawn through; if this is imperceptible, the ladder becomes treacherous.
* Steel ladders provide a strong, durable solution but are usually heavier than both wood and aluminium. They are typically seen as step ladders (sometimes with timber treads) or as permanent vertical ladders fixed to a wall.
