That's an excellent and very practical question! Whether your outdoor benches can brave a heavy winter really depends on a few key factors. Let's break it down so you can make the best decision for your furniture.
First, consider the material. Modern all-weather benches made from powder-coated aluminum, teak, cedar, or high-quality poly-resin (like Polywood) are champions in the cold. They're designed to resist moisture, freezing temperatures, and snow load. A thick blanket of snow won't inherently damage them. On the other hand, benches made from wrought iron (which can rust), untreated softwoods, or those with delicate cushions and fabrics are much more vulnerable and are better off stored.
Even for durable benches, a little prep goes a long way. If you leave them out, ensure they are on a level surface to prevent stress from ice heaving. A protective cover made of breathable fabric is highly recommended—it shields from ice melt chemicals, dirt, and relentless moisture while allowing air circulation to prevent mold. Avoid piling snow directly on them for extended periods, though occasional snowfall is fine.
So, should you store them? If your benches are lightweight, made of non-weather-resistant material, or have significant sentimental or monetary value, storing them in a garage, shed, or under a covered patio is the safest bet. It eliminates all weather-related wear and tear.
In short, robust, all-weather benches can typically withstand a snowy winter with minimal preparation. For less durable or delicate pieces, cozy indoor storage is the clear winner. When in doubt, check the manufacturer's warranty and care instructions—they provide the best guidance for your specific bench.
