While you can technically place regular indoor throw pillows on your urban outdoor furniture, it is not recommended for long-term use. The primary issue lies in material durability. Indoor pillows are typically made from fabrics like cotton, linen, or velvet, which are not designed to withstand the elements. Sunlight will cause colors to fade rapidly, and rain or humidity will lead to moisture absorption, resulting in mold, mildew, and internal stuffing breakdown.
For a functional and stylish outdoor space, specially designed outdoor throw pillows are essential. They are constructed from solution-dyed acrylic, polyester, or other weather-resistant fabrics that are UV-protected, water-repellent, and quick-drying. Their fills are often made from hydrophobic materials that resist clumping. If you must use indoor pillows temporarily, be prepared to bring them inside after every use and accept a significantly shortened lifespan. For a carefree patio, investing in purpose-built outdoor cushions is the wise choice for both aesthetics and longevity.
