When you're setting up your patio furniture, it’s tempting to grab any cushion that looks good and fits the seat. But there’s a big difference between cushions made for the outdoors and the ones meant to stay inside. While they may seem interchangeable, using the wrong type in the wrong setting can lead to fading, mildew, or a soaked seat. Here’s a clear breakdown of what sets indoor and outdoor cushions apart, and whether you can swap them safely.
What are Indoor Cushions Made of?

Indoor cushions prioritize comfort and aesthetics. They’re usually filled with soft foam, down, or polyester fiberfill and wrapped in materials like cotton, velvet, linen, or microsuede. These fabrics feel cozy but aren’t designed to handle moisture, UV rays, or rough weather. The focus is on style and softness, not durability against the elements.
What are Outdoor Cushions Made of?

Outdoor cushions are built to survive the elements. Their covers are typically made from tough, weather-resistant fabrics like solution-dyed acrylic, olefin, or polyester treated with UV inhibitors. Inside, they’re often filled with quick-drying foam or polyester that resists mold and mildew. These cushions are designed to repel water, resist sun fading, and stay looking good even after a summer thunderstorm.
Can I Use Indoor Cushions Outdoors?
Technically, you can, but it’s not a good idea. Indoor cushions will soak up rain, fade in the sun, and become breeding grounds for mold if left outside. Unless you plan to bring them in after every use (and even then, you’re pushing it), they won’t hold up. Using indoor cushions outdoors is a quick way to shorten their lifespan.
Can I Use Outdoor Cushions Indoors?
Yes, and in some cases, it makes sense. Outdoor cushions are more rugged and easy to clean, making them a practical option for homes with pets, kids, or high-traffic areas. The trade-off is that they might feel firmer and less plush than indoor cushions. But if durability is your top priority, outdoor cushions can work just fine inside.
The main difference between indoor and outdoor cushions comes down to materials and durability. Indoor cushions are made for comfort and style in protected spaces, while outdoor cushions are designed to withstand moisture, sunlight, and wear. While you can use outdoor cushions indoors, the reverse doesn’t hold up. Choosing the right type keeps your furniture looking great and lasting longer. And when the season changes, don’t forget proper care, here’s how to store your outdoor cushions during the off-season to keep them in top shape for next year.
