What is the main purpose of using legs in theater?

The main purpose of using legs in theater is to mask the sides of the stage. Legs are tall, narrow curtains or drapes that are positioned at the side of the stage. They serve to conceal any backstage areas from the audience's view, maintaining the illusion of the performance and helping to focus attention on the action occurring center stage. This masking allows for a clean and polished production aesthetic, ensuring that the audience is fully immersed in the performance without distractions from visible equipment or personnel.

While enhancing sound or blocking light might be functions carried out by other elements of stage design, legs specifically cater to the visual presentation by providing a boundary that separates the performance area from the backstage. Similarly, additional seating is not a function of legs; instead, they are primarily decorative and functional elements that contribute to the overall theatrical experience.
