A swing set is television jargon for a reconfigurable set. Most shows have several fixed sets, usually a living room, kitchen, office, board room, etc where most scenes are set. They also have one or two swing sets with movable walls that are redecorated to fit the script's needs. Larger productions may have more than two, because it generally takes a day to redecorate the set and two shows are often filmed in one day. Swing sets are the sign of a professional production because they allow you to tell the story first hand, rather than characters wasting dialogue relating action that supposedly took place. They also indicate professionalism because swing sets are very expensive, as the set must be built and torn down every week.
