The answer depends on your furniture's materials and your local climate. Generally, high-quality all-weather materials like powder-coated aluminum, teak, certain metals, and synthetic resins (HDPE) can withstand winter exposure, especially with proper preparation. However, covers are highly recommended for most furniture to prevent moisture damage, UV degradation, and dirt accumulation, ultimately extending its lifespan.
For winter care, first clean furniture thoroughly. Apply protective oil to teak and sealants to wrought iron if needed. Use tight-fitting, breathable, waterproof covers designed for outdoor furniture. Elevate pieces to prevent water pooling. Avoid storing cushions outside; bring them indoors. In harsh climates with heavy snow, ice, and salt, covers are essential even for durable materials. Furniture with moving parts, fabrics, or lower-quality construction always requires winter covering or indoor storage. Proper preparation and covers are key to ensuring your furniture looks great for seasons to come.
