An inner stairway carrying frame (3) is mounted by a hinge (4) at one end of the outer
mounting frame (2) for movement between a raised stored position on the outer mounting
frame (2) and a lowered position extending downwardly from the mounting frame (2).
An expendable attic stair (5) is mounted on the inner frame (3). A pair of folding

carrying frame (3). A cable (8) connects between each folding support arm (6) and
an associated reel (9) mounted on a drive shaft (10) which is connected to a drive
motor (11). This drive motor (11) is operable to wind and unwind the cables (8) on
the reels (9) to raise and lower the attic stair (5) in a controlled manner.
