While it may be tempting to simply move your comfortable indoor cushions to your balcony or patio, it is generally not recommended. Regular indoor cushions are not designed to withstand the outdoor elements. Exposure to sun, rain, and humidity can cause them to deteriorate quickly.
The primary issue is moisture. Indoor cushions are typically filled with materials like cotton or standard poly-fill, which absorb water. Once wet, they become heavy, take a very long time to dry, and are prone to developing mold and mildew. This not only ruins the cushion but can also create an unhealthy environment. Furthermore, the fabric on indoor cushions is not UV-resistant. Prolonged sun exposure will cause the colors to fade and the fabric to weaken and tear.
For your urban outdoor furniture, you need specific outdoor cushions. These are crafted from durable, weather-resistant fabrics like solution-dyed acrylic or polyester. These fabrics are designed to repel water, resist fading from the sun, and inhibit mold growth. The fillings are also different, often using quick-dry foam or are designed to allow for better airflow. Investing in proper outdoor cushions will ensure your furniture remains comfortable, stylish, and durable for many seasons. If you must use an indoor cushion outside temporarily, be sure to bring it indoors immediately after use and never leave it exposed to rain.
