Out cold before the first exit.01 / 06
A flat, padded bed that covers the footwell gap.
The FlatRide™ base bridges the space in front of the back seat, so there's no drop for paws to slip into. The quilted cover takes the hair, mud and claws so your seats don't have to.

What it fixes
The mess stayson the cover.
Shedding season, muddy trail days. Put the cover down once and quit worrying about the back seat.
-
01
No gap to fall into
The FlatRide™ base covers the footwell, so your dog gets one flat surface instead of a drop between the seats.
-
02
Claws hit the cover
Nails dig into quilted fabric, not your leather or cloth.
-
03
Spills sit on top
Water and drool bead up on the quilted Oxford fabric instead of soaking into your seat.*
The difference
Most covers sag.This one has a floor.
A hammock is just fabric stretched between the headrests. When your dog steps toward the middle, it dips into the footwell — the same hole you were trying to cover. The FlatRide™ base is a rigid board that sits across that gap and gives the fabric something to rest on.
A hole in the middle of the seat
Your dog braces against the drop, slides forward on every stop, and ends up wedged in the footwell on long drives.
One flat bed, seat back to front seats
The board carries the weight instead of the fabric, so there's nowhere to slide into and your dog can lie down full length.
Will it fit?
Two minutes with a tape measure.
Most returns in this category happen because the cover didn't fit the car. Measure first and you skip the whole problem.
- Measure across your back seat
Door to door, along the seat. You need about 54 in (137 cm) of width.
- Measure front to back
From the back rest to the back of your front seats. You need 26–28 in (65–71 cm).
- Check your rear headrests
The straps loop around them. No rear headrests, no install.
Still not sure? Email us your car's make, model and year before you buy and we'll tell you straight whether it fits — including if the answer is no. And if it arrives and still doesn't work in your car, you have 90 days to send it back.

Where these come from: we're a new store, so we don't have our own reviews yet — and we're not going to borrow anyone else's. These are verified buyers of this exact product on our supplier's marketplace, translated from the original language. Country, date and the original text are shown on each one, including the critical one. Our own customer reviews will appear here as soon as the first orders land.

Looks solid. Haven't tested it yet, but the flat part is hard, which will be good for my Akita.

Seems solid. The floor is stiff, though not like a plank. We'll see how it holds up with a 32 kg Doberman.

★★★☆☆
The rigid bottom isn't really rigid, it's semi-rigid. A large dog (40 kg) bends it with no trouble, as if it were cloth. It all feels quite fragile.
Original (Italian): “Il fondo rigido non è propriamente da considerarsi tale ma semi rigido. Un cane di taglia grande (40kg) piega il fondo senza problemi come se fosse di telo. Sembra tutto molto fragile, staremo a vedere.”

Questions
Before you hit the road.
What you'll probably want to know first.
Will it fit my car?
Set up, it's about 54 in wide and 26–28 in deep, which fits the back seat of most sedans, SUVs and pickup trucks. The straps clip around the rear headrests. Email us your car's make, model and year before you order and we'll tell you straight whether it fits. Measure your back seat too — it takes a minute. And if it still doesn't fit, you have 90 days to send it back, used or not.
What is the FlatRide™ base?
It's the rigid board under the padded top that spans the footwell — the gap in front of the back seat where dogs slide down when you brake. With it in place, the back seat is one flat bed from the seat back to the front seats, rated to hold up to 220 lb. Soft hammocks without a rigid base sag into that gap; the FlatRide™ base is what keeps the surface flat.
Is it hard to put in?
No tools needed. Loop the straps around the rear headrests, clip the buckles, and lay the FlatRide™ base across the footwell.
Does it replace a harness?
No. It gives your dog a flat spot and protects the seat, but it won't hold them in place if you brake hard or crash. Use it together with a harness or a crate.
How do I clean it?
Shake off the loose hair, then wipe it with a damp cloth or run a vacuum over it. For the hair the vacuum leaves behind, use the glove that comes with it. Check the care label before you try anything else.
Does it smell when it arrives?
It can carry a faint factory smell straight out of the bag, like most new car covers. Unfold it and leave it out for a day before the first trip and it goes away.
How fast does it ship?
Shipping is free — we don't charge for it at any order size. It ships from a warehouse in the US to the lower 48 states and DC, and most orders arrive in about a week. You'll get a tracking number by email as soon as it's on the way.
When does the free glove arrive?
It ships separately from the extender, so the two packages can show up a day or two apart.
What's your return policy?
You have 90 days after your order arrives to send it back for a refund. Your dog can have already used it, and you don't need the tags or the original packaging — we'd rather you actually try it in your car than leave it in the bag.
What if it rips?
If the fabric rips or tears, or a strap or buckle fails in normal use within 90 days of delivery, send us a photo and we'll ship you a replacement. It doesn't cover chewing, cuts, or damage from anything other than everyday use.
Why are the reviews from Europe?
Because we're a new store and we'd rather show you real ones than invent them. The reviews on this page are from verified buyers of this exact product on our supplier's marketplace, where it has been selling longer in Europe than in the US. We show the country, the date and the original text of each one — including the critical review. As soon as our own customers start leaving reviews, those go here too.
How long does the launch deal last?
The $129.99 launch price and the free glove are for the first 30 days. After that, the extender goes up to its regular price of $159.99.
