Abstract

A modular ladder comprises a base having a back end and a front end. A vertical support is attachable to the back end of the base. The ladder also includes a stair section assembly comprising a plurality of steps. The stair section assembly has a front end and a back end. The front end of the stair section assembly is attachable to the front end of the base. The back end of the stair section assembly is attachable to the vertical support. The stair section assembly comprises a separate top step, whereby the top step is capable of being attached to the stair section and whereby the attachable nature of separate top step facilitates storing the ladder in a compact container which is smaller than the stair section and top step when placed in an assembled condition. A method of storing the ladder in a compact container is also disclosed.
