These sturdy patio chairs feature a heavy-duty iron frame with an ecoating finish, which uses electrically charged particles to coat the metal and prevent rust—ideal for coastal living and long-term outdoor use. The thickened metal frame adds durability, resisting rust and weather to stand up to damp air, while the carefully treated coated surface has a soft, delicate gloss and smooth touch, free of burrs or uneven spots. The chairs come in multiple packages with illustrated instructions, making assembly quick and easy, with all chairs installable within 1 hour.
