While it might be tempting to use plush indoor cushions on your outdoor furniture, this is generally not recommended and can lead to several problems. Indoor cushions are typically constructed from materials not designed to withstand outdoor conditions. They lack the crucial weather-resistant properties needed for longevity.
The primary issue lies in the fabric and filling. Indoor cushions often use natural fibers like cotton, linen, or velvet, which absorb moisture quickly. When exposed to rain or morning dew, these materials become a breeding ground for mold and mildew. The padding inside, usually made of standard polyester fiberfill or down, will also retain water, leading to a soggy, unpleasant mess that takes a long time to dry. This constant dampness can also cause the cushion's core to compress and degrade, ruining its shape and comfort.
Furthermore, indoor cushions offer no protection against the sun's powerful UV rays. The colors will fade rapidly, and the fabric will become brittle and weak, leading to tears and rips. They are also not treated to resist stains from pollen, bird droppings, or spilled drinks.
For these reasons, it is essential to use cushions specifically designed for outdoor use. Outdoor cushions are made from solution-dyed acrylics, polyester, or vinyl—fabrics that are water-resistant, quick-drying, and UV-protected. Their fillings, such as quick-dry foam, are engineered to repel moisture. For the best results and to extend the life of your furniture, always choose cushions rated for exterior use.
