Is there a collective name for the table/bench/chair configuration used by contestants on such as family TV game shows?


Prop or Theatrical Property - Wikipedia.

A prop is considered to be anything movable or portable on a stage or a set, distinct from the actors, scenery, costumes, and electrical equipment.

Eg: The only props used in the show are a table, a chair, and a glass of water. Cambridge Dictionary


The only game show I can clearly visualize in my mind is Jeopardy. There the contestants each have sort of a lectern. They stand side by side. Maybe we could call it a triple-lectern.

If you could supply an image or a sketch it would be helpful.
