When it comes to doormats, you’ll have three main styles to choose from: synthetic, rubber and coir. The best mat for you will vary based on your preferences. -Synthetic doormats: These doormats are made from polypropylene with a rubber seal around the edges. -Coir doormats: Coir mats are made from coconut husks, giving them a rustic look and abrasive texture, which is great for cleaning shoes. -Rubber doormats: These heavy duty mats clean shoes and trap water, and are often used in commercial kitchens.
