Just like other bedding products and clothing, it’s best to wash before use. Some may notice a slight odor upon unboxing, and this is completely normal and natural. Washing the sofa covers will remove the odor. Remember: Do Machine Wash Separately on Low & Do Drip Dry for the Best Results. (Tumble Dry Low is an Option but Drip Dry is Recommended). Do Not Iron, Do Not Bleach, and Do Not Dry Clean.
