[Problem] To provide a degree of freedom to methods for using movable bleachers. [Solution] In the present invention, movable bleachers are configured such that a plurality of tiers of floor bases move back and forth in conjunction with one another between a usage position at which the entirety of the floor bases are deployed in a staircase pattern, and a stowed position at which the entirety of the floor bases are aligned in the vertical direction, wherein the movable bleachers are characterized by being equipped with: legs for respectively supporting the plurality of tiers of floor bases so as to be movable back and forth in a horizontal state, and interlocking the floor bases by mutual engagement; a usage position altering means for extending/reducing a deployment length at which the entirety of the plurality of tiers of floor bases are deployed in the staircase pattern at the usage position, by altering mutual engagement positions; and chairs arranged side by side in a row on the floor bases, such that the front/rear direction position thereof can be altered so as to correspond to the usage position for which the deployment length has been extended/reduced. |
