Dog Backseat Extender Safety System
Create a more complete backseat travel space with the Animals Matter® Backseat Extender Safety System. Designed to help fill the open footwell area behind your vehicle’s front seats, this modular system gives your companion a more continuous, cushioned surface for car rides, errands, weekend travel, and longer journeys.
Use one Companion Backseat Extender to fill one footwell, two extenders to help fill both rear footwells, and the Companion Backseat Bridge to help close the center gap between them.
Designed for a More Complete Backseat
Fill the Footwell Gap
Open rear footwells can create an unstable drop-off area where dogs may step, slide, or fall during travel. The system is designed to help fill that space with supportive, cushioned structure.
Build the Right Setup
Use one extender for one side, two extenders for both rear footwells, and the Companion Backseat Bridge to help complete the center section.
Refined Vehicle Comfort
Crafted with supportive foam components and premium upholstery-grade covers, each piece is made to look tailored inside the vehicle while supporting your companion’s comfort.
HOW THE SYSTEM WORKS
The Backseat Extender Safety System is modular, allowing you to build the setup that best fits your vehicle, your companion, and the way you travel.
