A collapsible ladder comprises two stiles formed of telescopically collapsible sections (10), a plurality of rungs (11) each mounted between two sections of the respective stiles, and latch mechanisms located in the rungs for automatically locking the sections (10) of the stiles relative to one another when the sections are extended.
