Folding stairs have three segments (11, 12, 13) of ladder stairs connected by hinges. The first segment (11) of stairs is connected by an articulated joint with door frame (2) by means of hinge holders (3) fitted from inside to door frame wall, and during unfolding of these stairs rotation axle of the first segment of stairs does not change its position against door frame. Flap (4) is suspended to the first segment of stairs by means at least two couples of connecting rods (41, 42), which together with the first segment of stairs and the flap form four-bar linkage.
