A multifunctional ladder can be used as a staircase, depending on the need. It consists of three sections, they advance one of the other and create a breeze staircase, rather large. Sections are connected using automatic latches.
Multifunctional ladders are with retractable sections, telescopic, and folding sections, with sections that are collected. Which ladder is better depends on a certain situation. Transformers have much more capabilities. For example, they are able to create a M-shaped staircase or working platform. A folded ladder-transformer is quite convenient and very easily fit into a car trunk.
