While it might be tempting to use your cozy indoor cushions on outdoor furniture, this is generally a bad idea that can lead to ruined cushions and unnecessary expense. Regular indoor cushions are not designed to withstand the outdoor elements. They lack the specialized fabrics and fillings found in outdoor-specific cushions, which are engineered to resist moisture, mold, mildew, and fading from the sun.
When exposed to rain or even high humidity, indoor cushions will absorb water. This leads to several problems: the cushions become heavy and take a very long time to dry, creating a perfect environment for mold and mildew to grow inside the filling. Furthermore, the fabric is likely to fade and deteriorate quickly under direct ultraviolet (UV) rays, and the filling may break down, losing its comfort and support.
For the longevity of your cushions and the comfort of your outdoor space, it is highly recommended to invest in cushions specifically designed for outdoor use. These are made from durable, weather-resistant materials like solution-dyed acrylic fabric and are filled with quick-drying foam or polyester fiber. They are built to last through sun, rain, and changing seasons, protecting your investment and ensuring your outdoor furniture remains a comfortable retreat.
