This sofa bed cover has clear size requirements for compatibility: the back width must be between 62-73 inches (this is a mandatory fitting condition). For detailed dimensions, refer to the measurement guide in the images, we recommend measuring before purchasing. Crafted from a blend of 85% polyester and 15% spandex, the fabric is wrinkle-resistant and durable with a comfortable touch, making it ideal for families with children and pets. It effectively protects the sofa bed from daily wear and stains. Installation is simple: first locate the "BACK" label on the sofa cushion cover, stand behind the sofa to ensure the label is in the correct position, start covering the entire sofa bed from the back, and tuck excess fabric deeply into the sofa bed gaps for a convenient installation and snug fit. For cleaning and maintenance, it supports machine washing with water temperature ≤86℉. Wash separately on a gentle cycle, do not bleach or iron. Even if pet hair adheres to it, it can be easily wiped clean. Size: large. Color: Black.
