Using your regular indoor pillows on urban outdoor furniture might seem convenient, but it's a decision you'll likely regret. Indoor pillows are not designed to withstand the harsh elements of an outdoor environment and will quickly become ruined.
The primary enemies of indoor fabrics outdoors are sun, moisture, and mold. Prolonged exposure to direct sunlight will cause the colors of your pillows to fade rapidly and can weaken the fabric fibers, leading to tearing. A sudden rain shower will soak an indoor pillow through and through. Unlike weather-resistant outdoor cushions, indoor pillows lack quick-drying foam and protective barriers. This trapped moisture creates a perfect breeding ground for mildew and mold, resulting in unpleasant odors and permanent stains that are nearly impossible to remove.
Furthermore, indoor pillows can attract dust, pollen, and even pests when left outside. Instead of sacrificing your decorative indoor pillows, invest in purpose-built outdoor cushions. These are constructed from durable, solution-dyed acrylic or polyester fabrics that are UV-resistant, water-repellent, and mold-resistant. They are filled with quick-dry foam that allows water to pass through and evaporate quickly.
For occasional use, you can bring your indoor pillows outside temporarily but always bring them back inside immediately afterward. For a permanent solution, always choose pillows specifically rated for outdoor use to ensure your furniture looks great and your investment is protected.
