A durable, low-cost, disposable absorbent sheet of layers ultrasonically secured together, including a permeable top layer, an upper absorbent layer, an impermeable layer that prevents moisture passage, a lower absorbent layer, and a permeable bottom layer. The layers are ultra-sonically bonded at point locations, which provides a low-cost secure attachment and further provides an attractive pattern to the sheet. Also, the bonding forms depressions that facilitate entry of water into the absorbent layers. Repositionable adhesive on the bottom layer provides secure but repositionable attachment to a floor surface. An anti-microbial agent and/or an air freshening agent can be added to the absorbent layer as desired. |
