Seat covers are protective layers fitted over vehicle seats to mitigate wear, staining, and damage from environmental factors. Typically constructed from fabrics, vinyl, or synthetic materials, they secure via straps, hooks, or integrated elasticized systems. Designs range from universal fit to custom-molded configurations, specifying vehicle year, make, and model for precise contouring. Advanced covers may incorporate features like integrated airbags pass-throughs, heated seat compatibility, and moisture-wicking properties. Material selection impacts abrasion resistance, UV stability, and ease of cleaning, influencing lifespan and aesthetic maintenance.
