Can You Leave Outdoor Cushions Outside in the Winter?
As the days grow shorter and the air turns crisp, many homeowners begin preparing their patios and outdoor living spaces for colder months. A common question we hear at Cascadia Outdoor Cushions is: “Can I leave my outdoor cushions outside in the winter?”
The answer isn’t a simple yes or no. It depends on your climate, the type of fabric used in your custom outdoor cushions, and how much protection you want to give your investment. Let’s break it down so you can make the best decision for your outdoor living space.
Understanding Custom Outdoor Cushions
High-quality outdoor cushions, like those crafted at Cascadia, are designed to endure exposure to sun, rain, and everyday outdoor living. Most are made with performance fabrics such as Sunbrella®, Outdura®, Tempotest®, or Revolution®—all engineered to resist fading, repel water, and discourage mold and mildew.
But “outdoor” doesn’t mean indestructible. Even with water-resistant fabrics and quick-drying foam, prolonged exposure to snow, ice, and freezing temperatures can take a toll. Fibers expand and contract when frozen, seams may weaken, and dirt or moisture trapped inside can create the perfect environment for mold.
How Winter Weather Affects Outdoor Cushions
Mild Climates
If you live in a region with mild winters—think southern states where freezing temperatures are rare—you may be able to keep your patio cushions outside with little risk. Occasional rain or chilly nights won’t cause significant damage, especially if cushions are covered or stored in a protected space like a screened porch.
Harsh Climates
For those in northern states or areas with heavy snowfall, freezing rain, and subzero temperatures, leaving your cushions outside all winter is not recommended. Even water-resistant fabrics like Sunbrella cushions can eventually absorb moisture when buried under snow or ice for weeks at a time. That moisture can freeze inside the cushion, weakening the structure and reducing its lifespan.
Mold & Mildew Risks
Most custom outdoor cushion fabrics resist mold and mildew, but resistance isn’t the same as immunity. If cushions stay damp and dirty—say, from melting snow and debris—fungi can develop. Once mildew takes hold, it can be difficult to remove completely.
How to Protect Your Outdoor Cushions in Winter
If you want your cushions to stay vibrant and comfortable for many years, winter protection is essential. Here are the best options:
1. Indoor Storage (Best Option)
Bring your cushions indoors during the winter months. A garage, basement, or spare closet works perfectly. Just make sure they’re clean and completely dry before storing.
2. Outdoor Storage Boxes
If indoor space is limited, invest in a waterproof outdoor storage box. These are designed to keep outdoor pillows and cushions dry while still being close at hand.
3. Protective Covers
If storage isn’t an option, use heavy-duty furniture covers. These protect against snow, rain, and debris. Choose covers that are breathable to prevent condensation inside.
4. Regular Maintenance
Check cushions periodically throughout the winter, even if they’re stored away. Look for early signs of mold, mildew, or fabric stress. A quick inspection now saves bigger headaches later.
Practical Tips Before Storing Your Cushions
Clean First: Brush off dirt, leaves, or pollen. Use mild soap and water for spot cleaning.
Dry Thoroughly: Never store damp cushions—moisture is the enemy.
Label or Group by Furniture Set: Makes it easier to reset your patio in spring.
Order Early for Next Season: If you plan on updating, winter is a great time to select new custom outdoor cushions. Lead times are often shorter, and your cushions will be ready for spring.
The Cascadia Recommendation
So, can you leave outdoor cushions outside in the winter? Technically, yes—especially in milder climates. But at Cascadia Outdoor Cushions, we recommend storing them away whenever possible. Proper care now ensures your cushions will last longer, look better, and stay comfortable for many years.
Your outdoor space is an investment, and your cushions are the comfort and style centerpiece of that space. Treat them with care, and they’ll reward you with beauty and durability season after season.
