Coasters Your mom was right—put a coaster under it! Protect your tables and countertops from water rings and condensation damage with coasters that are as fashionable as they are functional. No more worrying about a drink puddles or "sweat" on surfaces, coasters keep moisture away from coffee and end tables and they don’t scratch or mar furniture. Try these in the bedroom on nightstands, the home office on desks, or anywhere you might set a drink down.
