A vehicular seat bench cover system is provided. The vehicular seat bench cover system provides coverage of each section of the seat bench—the passenger-side, driver-side, center sections of both the back and seat portions—either circumscribed or enclosed in separate covers or covered by the separate cover sections being joined. Mindful that each section can independently move between an upright condition and a folded condition, the seat bench cover system provides a section cover for each section, wherein each separate cover provides a detachable fastener along one or both longitudinal edges so that adjacent section covers can be joined or be independently circumscribed by different permutations of the seat bench cover system depending on whether that section and an adjacent section are in the upright condition or folded condition relative to each other.
