The short answer is yes, you should cover your all-weather outdoor furniture during the winter, even if it's marketed as durable. While materials like powder-coated aluminum, teak, or high-quality resin wicker are designed to withstand the elements, proactive winter protection significantly extends their lifespan and keeps them looking new.
"All-weather" does not mean "all-climate" or "indestructible." Prolonged exposure to winter's harsh trio—moisture, freezing temperatures, and UV rays—can still cause cumulative damage. Moisture can seep into microscopic pores and expand when frozen, potentially leading to cracks or weakening joints. UV rays, present even on cold, sunny days, can gradually fade colors and degrade materials over time. Debris, dirt, and fallen leaves can also stain surfaces or promote mildew.
Using a high-quality, breathable cover is the best defense. Avoid plastic tarps, as they trap moisture underneath, creating a damp environment ideal for mold and mildew. A breathable, waterproof fabric cover shields furniture from snow, ice, and dirt while allowing condensation to escape. Ensure the furniture is clean and completely dry before covering it. For optimal protection, consider storing lightweight pieces in a shed or garage. Adding a layer of furniture wax or sealant (appropriate for the material) before covering provides an extra barrier.
Taking these steps prevents unnecessary wear, saves you money on replacements, and ensures your furniture is ready for enjoyment when spring arrives. A little effort in the fall guarantees many more seasons of comfortable and stylish outdoor living.
