ABSTRACT:
A retractable stairs-like stand has rows of seats on moveable floor-bases arranged in a stair-like manner for use in an auditorium or stadium-like application. A variety of seating styles can be accommodated due to the retracted storage position used wherein the steps are shifted to all be in vertical alignment, and the seats are stored in a nested configuration with corresponding seats in vertical alignment to provide a more compact arrangement.
