Each side rail may be coilable and resilient, or may be foldable and comprised of a plurality of hingedly connected fold sections. The first and second side rails preferably are formed from a single stringer having a first portion and a second portion, the stringer being made of a material to permit the stringer to bend for bringing the second portion in a confronting spaced relationship relative to the first portion to define the first and second side rails. The stringer may be made of a coilable resilient material or of a foldable material comprised of a plurality of hingedly connected fold sections. Each of the rigid steps preferably comprises an L-shaped step piece having a tread portion and a riser portion, or each of the rigid steps may comprise a flat tread and the toy staircase may further comprise at least one brace portion connectable between the side rails. Each of the rigid steps may comprise a tread portion hingedly attached to a riser portion, and there may be a plurality of the hingedly attached tread and riser portions hingedly attached to each other to form a continuous set of the rigid steps.
