Abstract
This invention describes a transparent chair mat having anti-static qualities. The chair mat is substantially transparent thereby permitting the carpet thereunder to be readily seen. The chair mat can be gounded or not, as desired. This anti-static chair mat enables castered chairs to roll over it without the person sitting in the chair generating excess static-electricity.
