They protect the original seat fabric from everyday wear and tear, as well as any spills and associated mess from kids or pets in the car. A set of seat covers can actually help preserve the resale value of your car. At MicksGarage.com, we have a wide variety of seat covers in a range of styles and fabrics to suit all tastes and budgets. Our seat covers are compatible with safety features such as seat airbags and many have cut-outs for safety belts.
