The term 'STAGE support' can be broken down into two words: 'PROP' and 'STAGE'. A PROP is an object used on STAGE during a performance, such as a chair or a table. STAGE support refers to the people who help with the setup and maintenance of the props used in a production. They are responsible for ensuring that the props are in the right place at the right time, and that they are safe and secure. They also help with the storage and transportation of the props.
