Retractable stands, also known as movable stands, are named relative to fixed stands. When the retractable stand is extended into a staircase shape, the seats on the stand provide a comfortable viewing experience for the audience. When it is retracted into a box-like shape (resembling a drawer), it occupies very little space, freeing up the venue for other purposes. Retractable stands can make full use of the limited indoor area and meet the demand for multiple seating arrangements under different functional situations. Retractable stands are widely used in gymnasiums, conference rooms, demonstration rooms, studios, multi-function halls, etc.
