Using this sofa cover is easy. Just stretch it over your sofa, making sure it fits snugly. It's designed to be elastic, so it should adapt well to different sofa shapes. When it gets dirty, you can simply remove it and throw it in the washing machine. Make sure to follow the normal washing instructions for polyester and spandex materials. For maintenance, avoid using sharp objects near the cover to prevent tears. If it loses its elasticity over time, don't worry. Just give it a gentle stretch when you put it back on the sofa.
