Yes, Smartstage is designed to be built over stadium seats. We make different leg systems to do so, but before recommending the most efficient method, we need to get an idea of height, and depth. The fast and easy solution, is using the fastfold frame, however, it will need the open floor area for it, which is 4' x 8'. If the legs need to be positioned BETWEEN seating, or other obstacles, then we propose single legs. 

Please remember, for safety, whenever a Smartstage platform is set higher than 30-36 inches, you need diagonal supports, which we offer.
