Wrought iron chairs are traditionally used outdoors with bistro tables, but they are also perfectly acceptable for indoor use. They are perfect when used in the kitchen with any small table, for that bistro look and feel, right at home. If the chairs will be used outdoors, make sure any cushion you use is waterproof and weather resistant.
