A performance surface is a flooring suitable for dance or sport. Performance surfaces are normally laid on top of, or are part of, a sprung floor to produce a complete dance floor or sports floor. Dance performance surfaces made of sheet vinyl are also called dance floors and marley floors. They are called marley-type floors from a very popular reversible vinyl flooring manufactured for years until about 1978 by Marley Floors Ltd.
