It might be tempting to grab those comfortable indoor pillows to spruce up your patio furniture, but this is generally a bad idea that could lead to ruined pillows and unnecessary expense. Regular indoor pillows lack the specialized materials and construction needed to withstand outdoor conditions. They quickly fall victim to moisture, which leads to mold and mildew growth inside the filling, creating an unhealthy and unpleasant seating area. Furthermore, indoor fabrics fade rapidly under the sun's UV rays and offer no protection against pollen, dirt, or accidental spills.
Unlike their outdoor-specific counterparts, indoor pillows are not designed for durability in the elements. Outdoor cushions are crafted from solution-dyed acrylics or polyester with UV inhibitors and are filled with quick-drying materials. They are also easier to clean and maintain for the long term. For the health of your pillows and the comfort of your outdoor space, investing in properly rated outdoor cushions is the only wise choice.
