An adjustable stairway (10) has a first frame section (11) with fixed steps (15). A second frame section (22) is coupled to the first frame section (11) such that relative movement there between can take place such that the stairway is adjustable between a compacted form and an extended form. The stairway (10) also has one or more floating steps (25). Engagement abutments (29) are coupled to the second frame section (22) and are engagable with the floating steps (25) so that the floating steps (25) are progressively raised and lowered as the stairway (10) is moved between the extended and compacted forms.
