ABSTRACT:
A multi-purpose mat has open and folded configurations. The mat includes a base and a plurality of sidewalls disposed about a periphery of the base. A first resilient flexible slat is disposed within one of the sidewalls and a second resilient flexible slat is disposed within the remaining sidewalls. The slats provide means for reinforcing the sidewalls and also provide a spring-like effect that allows the mat to automatically rollout into the open configuration from the folded configuration. The sidewalls fold about the periphery of the base; the sidewalls moving from a position generally adjacent to the base to a position generally perpendicular to and extending generally upwardly from the base when the mat is moved from the folded configuration to the open configuration.
