Abstract
Embodiments of the present invention are directed to a cushioning mat with a porous backing. The cushioning mat may include a surface layer of face fabric, a layer of open-cell, viscoelastic foam, and a backing in the form of a porous underlay. The porous underlay may have openings through which water penetrating the cushioning mat can escape. The porous underlay may be PVC-coated polyester. Additionally, a layer of jersey knit cloth may be interposed between the porous underlay and the layer of open-cell, viscoelastic foam to promote bonding properties.
