Leaving outdoor furniture outside during winter is a common dilemma for many homeowners. While it might seem convenient, the answer isn't a simple yes or no; it heavily depends on the material your furniture is made from.
Harsh winter conditions—snow, ice, rain, and freezing temperatures—can cause significant damage. Metal can rust, wood can warp and crack, and plastics can become brittle and fade. Cushions are prone to mold and mildew.
For durable materials like aluminum, certain treated metals, and high-quality all-weather resins, leaving them outside might be acceptable if they are thoroughly cleaned and protected with high-quality, waterproof covers that are securely fastened. However, even these materials benefit from being placed in a sheltered spot.
For more vulnerable materials like wrought iron (which can rust), most wood (especially teak that isn't regularly oiled), and wicker, storage is highly recommended. The safest approach for these pieces is to clean them and store them in a dry, covered area like a garage, shed, or basement.
Ultimately, storing your furniture is the best way to preserve its appearance and longevity. If you must leave it outside, invest in robust covers and understand that some wear and tear is inevitable. Taking the time to protect or store your furniture properly in the fall will save you money and effort on repairs or replacements come spring.
