Abstract
Certain aspects of the present disclosure provide techniques for a mobile adjustable stairway which has a first frame section which is adapted to be mobile and has fixed steps and a second frame section coupled to the first frame section such that relative movement there between can take place whereby the stairway is adjustable between a compacted form and an extended form. A set of floating steps is provided whereby each floating step is adapted to be progressively raised and lowered as the stairway as the second frame section is moved relative to the first frame section between the compacted and extended forms. The stairway also has a set of first components associated with each floating step operable to laterally stabilize the floating step when in the extended form; and a set of second components associated with each floating step operable to longitudinally stabilize the floating step when in the extended form.
