A car seat cover is a protective accessory designed to fit over the seats of a vehicle. It helps to shield the original upholstery from spills, stains, and wear, making it easier to maintain the car's interior. Car seat covers come in various materials, including fabric, leather, and neoprene, and can be customized to match the vehicle's style. These covers are available in different sizes and designs to accommodate various types of seats, such as bucket seats and bench seats. Many car seat covers are also machine washable, providing a convenient way to keep the interior clean and fresh.
