U.S.-made WeatherTech products, including floor and cargo mats, exterior deflectors and vehicle covers, offer protection against water, condensation dirt and assorted spills. But did you know the company also sells a product that protects your furniture from the same damage? The clever set of drink coasters is made from the same material and patterns used to produce floor mats, only on a much smaller scale, of course. WeatherTech coasters are heat-resistant and their built-in groves and channels are designed to hold spills just like regular floor mats, which is something a traditional flat coaster can’t do. A set of four floor-mat coasters sells for $10 through www.weathertech.com.
