Whether you can leave urban outdoor furniture outside throughout winter depends primarily on material construction and local climate conditions. All-weather materials like powder-coated aluminum, teak, and high-quality resin wicker typically withstand year-round exposure when properly maintained. However, extreme winter conditions with heavy snow, ice, and freezing temperatures can accelerate wear even on durable materials.
For comprehensive protection, consider storing lightweight furniture in dry areas during harsh winters. Apply protective covers specifically designed for outdoor use, ensuring they breathe to prevent moisture trapping. Clean furniture thoroughly before storage to prevent mold and mildew growth.
Elevate furniture from wet surfaces using feet or pads to prevent water damage. Remove cushions and store them indoors during extended cold periods, as they retain moisture and take longer to dry in cold weather. Regular maintenance including cleaning and applying protective sealants will significantly extend your furniture's lifespan regardless of storage decisions.
