According to an embodiment of the present invention, a multi-step system for seats comprises a first seat step, a second seat step, and a third seat step respectively connected to a first seat, a second seat, and a third seat whereon audiences can sit. The first seat step, the second seat step, and the third seat step make up a three-stage seat step with relative position movement to make the audiences sit on all of the first to third seat steps. The second seat step is hidden under the third seat step to lose a seat function of the second seat while maintaining a seat function of the third seat connected to the third seat step, thereby making a two-stage seat step. |
