Toland Doormats come with non-skidding, rugged durgan backing and polyester felt top that is soft to step in! They are durable with rounded corners. Toland uses the finest process to permanently dye the fabric so that the mats are bright and vivid in color. They are non-fading and are resistant to mildew. Toland Doormats comfortably fit into standard 18" x 30" mat holders or trays (sold separately). Toland mats are thinner and flimsier than most other brands. They do not have rubber backing.
