The answer depends on your cushions' materials and your local climate. Generally, it's advisable to bring cushions indoors or store them in a dry place during harsh weather, heavy rain, or extended periods of non-use.
Most urban outdoor cushions are made from weather-resistant fabrics like solution-dyed acrylic, polyester, or vinyl-coated materials. These fabrics resist fading, mildew, and moisture. However, "weather-resistant" does not mean "weatherproof." Prolonged exposure to direct sun, torrential rain, or freezing temperatures can degrade even the best fabrics over time, causing fading, mold, or reduced filling loft.
For longevity, consider these tips:
1. Check the manufacturer's label for specific care and weatherproof ratings.
2. Use waterproof storage boxes or a dedicated outdoor storage bench for quick protection.
3. For frequent use, a fitted waterproof cover for the entire furniture set offers good protection.
4. Choose quick-dry foam fillings over traditional polyester fiberfill if buying new cushions.
5. Brush off debris and ensure cushions are completely dry before storage to prevent mildew.
Ultimately, bringing cushions inside is the best practice for extending their life and appearance. If leaving them outside, ensure they are designed for all-weather use and have proper protective covers. Your cushions will stay fresher and more comfortable with consistent care.
