The superior non-skid features of the Emanuele Bianchi Design Seat protectors keeps them securely anchored to your seats. A layer of rubberized anti-skid mesh covers the entire underside, wide Neoprene belts fit securely around the edge of the seat base, and two tucking inserts fit snugly between the seat base and back rest.

Our clever headrest belts can be used to cross around the seat shoulder when headrests are not available. The STANDARD version Standard Rear Seat (52\"W x 48\"H) is perfect for Car sizes and Small Trucks.
