Boot Liners For Citroen Ds3 Novline From 2010 to present Available here. A boot liner, also called a boot mat, is a protective cover designed to fit in the boot or cargo area of a car. It is usually made of rubber or plastic, and it is specifically shaped to match the contours of your vehicle's boot. Boot liners protect the upholstery from spills and stains, and they are removable and easy to clean. Boot mats are designed to withstand wear and tear, protecting the original carpet from stains, scratches, and scuffs. Keeping the boot area in good condition can help maintain your car's resale value. While universal boot mats can fit more models, custom-made boot mats are specifically designed for a particular model, ensuring a perfect fit. Non-slip boot mats are becoming more popular because they help keep items in place during transit, reducing the chance of them shifting or rolling around.
