Abstract
An activity field is surfaced with a cushioned, resilient rubber mat over a hard undersurface. One area of the field is subject to participant impact potentially resulting in injury. That area is provided with a closed cell shock absorbing foam pad between the rubber mat and the hard undersurface to permit the mat to flex restrained by the foam pad to attenuate an impact. The rubber mat is bonded to the pad by a flexible adhesive and both the mat and the pad are bonded to said undersurface. The mat extends beyond the perimeter of the pad.
