Why Choose Sterling Automotive Design?
ISOFIX & M1 Certified Rear Seat Conversions
When choosing a rear seat conversion for your Defender, safety and compliance should be just as important as the finished appearance. Every Sterling Automotive Design rear seat conversion is designed to provide complete peace of mind, with ISOFIX child seat mounting points and an M1-certified rear seating system included as standard.
ISOFIX Child Seat Mounting
Every conversion includes integrated ISOFIX anchor points, allowing compatible child seats to be securely fitted directly to the seat frame. ISOFIX provides a safer, simpler and more secure method of installing child seats compared with using seat belts alone, giving parents confidence every time they travel. Unlike some conversions where ISOFIX is unavailable or offered as an optional extra, every Sterling rear seat conversion includes ISOFIX as standard.
M1 Certified Rear Seating
Our approved rear seating systems are M1 certified, meaning they have been designed and tested for passenger vehicle use to recognised safety standards. This certification covers the complete seating system, including the seat structure, seat belt mounting points and head restraints, ensuring the installation is suitable for carrying rear passengers.
Complete Confidence
Every Sterling rear seat conversion is professionally installed by our experienced in-house technicians and supplied with the relevant certification documentation. Once your conversion is complete, your Defender is ready to enjoy with family, passengers and everyday use, knowing your seating system has been installed to the highest standards.
