Abstract: A foldable ladder having two rails with several rungs pivotally mounted on each end to rail extensions. The rail extensions are fixed to the rails and extend towards each other. A pivot joint in each rail extension connects a common rung to allow the rung to be pivoted on two of its ends. To prevent the normally pivotally joined rungs from moving when the ladder is in an opened position, a bracket is slidably mounted on the top and bottom ladder rungs.
