Retractable stands, also known as movable stands, are named in contrast 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 area inside, meeting the multi-seating requirements for different functional situations. Retractable stands are widely used in gymnasiums, conference rooms, demonstration rooms, studios, multi-function halls, etc.
