a chair;
a retaining element supported by the chair;
a platform, wherein the platform supports the chair; and
an activity rail assembly rotatably attached to the chair, the activity rail assembly having a horizontal activity rail portion and a mechanism for extending and retracting the activity rail assembly; wherein:
