We have two large Goldens and this extender turned our F-150 backseat into a full dog lounge. The hard bottom doesn't sag at all — both dogs ride on it without sliding. The door panels are genius, our interior doors used to get destroyed. Threw the whole thing in the wash after a muddy hike and it came out perfect. Worth every penny.

What's included in the box?

Every order includes the Ruff Liners backseat extender with hard bottom (3 removable reinforced plastic inserts), integrated door panel protectors (both sides), quilted waterproof seat cover, zippable center console cover with mesh window, corner anchor straps, adjustable seat belt zipper openings, and non-slip backing. No tools or complicated installation — sets up in under 2 minutes.

How much weight can it hold?

The hard bottom extender supports up to 400 lbs thanks to 3 removable reinforced plastic inserts. That's strong enough for multiple large-breed dogs riding together — without sagging, flexing, or collapsing into the footwell. The rigid platform gives your dog a stable, flat surface that won't shift during turns or sudden stops.

Will it fit my vehicle?

We offer two sizes. Standard Size fits cars, mid-size SUVs, and small trucks — including Tesla Model 3/Y/S, Toyota RAV4/4Runner/Tacoma, Honda CR-V/Civic/Accord, Jeep Wrangler/Cherokee, and more. XL Size fits full-size trucks and large SUVs — including Ford F-150/F-250/Expedition, Chevy Silverado/Suburban, Ram 1500/2500, Toyota Tundra, GMC Sierra, and more. Check the size chart in the product images for exact dimensions.

How do I clean it?

The quilted fabric is 100% waterproof — most messes wipe clean with a damp cloth. For deeper cleaning, remove the hard bottom inserts and machine wash the fabric cover on a gentle cycle. Hang dry for best results. The waterproof coating repels liquids, mud, drool, and pet hair so your car interior stays protected.

Every Detail Designed for Dogs (and Their Humans)

  • 400-lb Hard Bottom

    3 removable reinforced plastic inserts create a rigid, flat platform that bridges the backseat gap. Supports up to 400 lbs without sagging — strong enough for multiple large dogs riding together.

  • 32% More Riding Space

    The seat extender fills the footwell gap and creates one continuous flat surface across the entire backseat. Your dog gets a full bed-sized platform instead of a narrow hammock.

  • Patented Door Protection

    Integrated door panel covers shield both car doors from scratches, drool, and muddy paws. Works with doors open or closed and windows up or down. U.S. Patent #12,221,024.

  • 100% Waterproof

    Heavy-duty quilted fabric with waterproof backing repels water, mud, drool, and accidents on contact. Wipe clean with a damp cloth or machine wash on gentle. Your seats stay bone dry.

  • Seat Belt & Anchor System

    Adjustable zipper openings provide full access to seat belts and child anchor seat systems. Corner anchor straps lock the cover in place so it won't shift, bunch, or slide during the ride.

  • Non-Slip Backing

    The underside features non-slip material that grips your seats and keeps the cover locked in position. Combined with the corner anchors, the platform stays stable even during sharp turns and sudden braking.

  • Soft Padded Surface

    The quilted top layer provides cushioned comfort that turns your backseat into a cozy dog bed. Soft enough for long road trips but durable enough to resist scratching and tearing from nails.

  • Center Console Cover

    The zippable center console cover with mesh window lets you keep an eye on your dog while protecting the console area. Zip it open or closed depending on whether you need armrest access.

  • Universal Fit — 2 Sizes

    Standard Size fits cars, mid-size SUVs, and small trucks. XL Size fits full-size trucks and large SUVs. Adjustable straps and velcro ensure a snug, custom fit in virtually any vehicle.

    Your Backseat Is Destroying Your Car's Value

    Muddy paws on the leather. Claw marks on the door panels. Drool soaking into seat fabric that never fully dries. Dog hair embedded in every crevice.

    Regular seat covers slip, sag into the footwell, and leave half your backseat exposed. Your dog slides around on turns and your doors take the worst of it.

    The Ruff Liners backseat extender bridges the gap, creating a flat 400-lb platform with integrated door protection on both sides. Waterproof, scratch-proof, machine washable — and installs in under 2 minutes with zero tools.

    Patented Door-to-Door Protection — Built Like No Other Cover

    Most seat covers stop at the seat. Ruff Liners wraps your entire backseat — doors included. The patented integrated door panel protectors shield both car doors from scratches, drool, and muddy paw prints without blocking the door from opening or closing.

    The 100% waterproof quilted fabric with non-slip backing keeps everything locked in place. The hard bottom platform with 3 reinforced inserts holds up to 400 lbs — no sagging, no collapsing into the footwell, no sliding on turns.

    – 32% more riding space with full backseat gap coverage
    – Adjustable seat belt zipper openings for seat belts and child seats
    – Zippable center console cover with mesh visibility window
    – Corner anchor strap system for a secure, shift-free fit
    – Machine washable on gentle cycle — hang dry

    From Install to Road Trip in Under 2 Minutes

     

    Install in Under 2 Minutes

    Drape the cover over your backseat, clip the headrest straps, and secure the corner anchors. Slide the 3 hard bottom inserts into the extender platform. The non-slip backing grips your seats instantly — no tools, no drilling, no permanent modifications to your vehicle.

    Full Door-to-Door Coverage

    The patented door panel protectors wrap both car doors, shielding them from scratches, drool, and muddy paws. Open the doors, close them, roll the windows up or down — the protection stays in place. Your seats, doors, console, and floor gap are all covered from a single product.

    A Safer, More Comfortable Ride

    The 400-lb hard bottom platform gives your dog a flat, stable surface — no slipping into the footwell gap, no sliding on turns, no anxiety from an unsteady seat. Soft quilted padding on top makes every ride comfortable while non-slip backing and corner anchors keep everything locked in place.

    Machine Washable — Stays Fresh

    The 100% waterproof fabric repels water, mud, drool, and accidents on contact. For daily messes, wipe clean with a damp cloth. For deeper cleaning, pull out the hard bottom inserts and toss the cover in the washing machine on gentle. Hang dry and reinstall — looks and smells brand new every time.

    Built for Every Dog, Every Drive

    • Road Trips & Daily Drives

      Whether it's a 10-minute vet trip or a cross-country road trip, your dog rides on a stable, padded platform. No more sliding off seats, falling into footwells, or scratching up your leather on every turn.

    • Muddy Hikes & Beach Days

      Let your dog jump in soaking wet and covered in sand — the 100% waterproof fabric and door panel protectors keep every surface shielded. Wipe clean or machine wash when you get home.

    • Multi-Dog Families

      The 400-lb hard bottom platform supports multiple large dogs riding together. The 32% extra space means everyone has room to spread out — no more cramped, overlapping, anxious backseat rides.

      Real Reviews from Real Dog Owners

      See why dog owners are upgrading from flimsy seat covers to full backseat protection.

      • "We have two 80-lb Labs and our Silverado backseat was getting wrecked. The XL size fits perfectly and the hard bottom doesn't sag at all — both dogs ride on it like a bed. The door panels are the real MVP though. Our interior doors used to look like a crime scene after every hike. Not anymore."

        Jason K.

      • "I tried three different seat covers before this one. They all slipped, bunched up, and left half the seat exposed. This extender actually stays put — the anchor straps and non-slip backing make a huge difference. The waterproofing is legit too. My Golden came back soaked from the lake and the seats underneath were bone dry."

        Michelle R.

      • "Got the Standard size for my RAV4 and it fits like it was custom made. My dog used to hate car rides because she'd slide off the seat. Now she just hops up on the platform and lays down the whole drive. The center console zipper is a nice touch — I can still use the armrest when she's not in the car. Machine washed it twice already and it looks brand new."
