Dog Car Seat Extender with Hard Bottom – Waterproof Hammock-Style Back Seat Cover for Cars, SUVs & Small Trucks – Pet Travel Mat with Non-Slip Base, Scratchproof 600D Oxford – Black

About this item

• Turns the Entire Back Row Into One Level Platform — The rigid bottom panel spans the full rear seat width and bridges the footwell, converting the back row into a single flat surface. Small, medium, and large dogs can stretch, sit up, and shift positions without the surface sagging or tilting. No more curling into a tight ball between seat edges. No more paws slipping into the footwell during hard braking.
• Fills the Footwell Gap Where Dogs Slip Through — The most common travel accident is a sudden stop throwing a loose or tethered dog into the footwell. This extender eliminates that gap entirely, creating a flat plane between the rear bench and the front seat backs. The hard bottom doubles as a load-bearing barrier — your dog cannot slide off the rear seat edge or fall between the seats. Pair with a crash-tested seat belt harness for full protection.
• Waterproof, Non-Slip, and Built to Last — The one-piece cover wipes clean in seconds: mud, spilled water, wet fur, and the occasional accident lift off with a damp cloth, no scrubbing needed. The non-slip backing and headrest straps keep the extender locked in place on sharp turns and uneven roads, without sliding forward or bunching under your dog. The 600D Oxford outer shell resists scratches from claws and holds up to daily entry and exit without fraying.
• Fits Sedans, SUVs, and Small to Mid-Size Trucks — Measures 50.8 × 23.6 inches. Designed for vehicles with a continuous rear bench and standard front headrest posts. The extender anchors by strapping directly to the headrests — no tools or vehicle modifications needed. If your vehicle has second-row captain's chairs with a fixed center console, this extender will not fit.
• Tool-Free Setup in Under a Minute — Unfold, lay flat across the rear seat, and hook the adjustable straps around the front headrest posts. No tools, no hardware, no permanent installation. To remove, unclip the straps and fold the extender flat — stores behind a seat or in the trunk without consuming cargo space.
