Companion Backseat Extender® for Dogs

Create a more complete, comfortable backseat travel space with the Animals Matter® Companion Backseat Extender® for Dogs, part of the Backseat Extender Safety System. Designed to help fill the open footwell area behind your vehicle’s front seats, the extender adds structured, cushioned support where there would otherwise be an open drop-off space between the front and rear seats.

Use one Companion Backseat Extender® behind a single front seat, or use two extenders with the Companion Backseat Bridge to help fill both rear footwells and the center gap for a more continuous, comfortable backseat surface.

Build the Backseat Extender Safety System

The Backseat Extender Safety System is a modular three-step travel support system designed to help create a wider, more stable-feeling backseat platform for your companion.

Step 1: Start with Two Backseat Extenders

Place two Animals Matter® Companion Backseat Extenders® in the rear footwells behind the front seats to help fill both open footwell spaces and create a wider cushioned backseat platform.

Step 2: Add the Animals Matter Backseat Bridge

Place the Companion Backseat Bridge between the two installed extenders to help fill the center gap and create a more continuous backseat surface.

Step 3: Complete the System

With both rear footwells and the center gap supported, the system helps create a more complete, cushioned, and stable-feeling backseat travel area for your dog.

Why This Travel System Is Different

The Companion Backseat Extender® is more than a loose cushion or basic car filler. It is part of a modular backseat support system designed to help reduce open footwell gaps where dogs may step, slide, or fall during travel.

Crafted with a supportive CertiPUR-US® certified foam component, each extender provides structure without the weight of hard plastic or wood. The premium upholstery-grade fabric cover feels soft, tailored, and refined inside the vehicle, while the removable zippered design makes care simple between everyday errands, weekend drives, and longer road trips.
