SHARLOVY XL Truck Back Seat Extender for Dogs (hard-bottom hammock) – waterproof back seat cover
Product description
The essentials
If you’re ferrying a larger dog in a pickup or large SUV, the rear bench can become a bit of a battlefield: muddy paws, slipping around on the seat, and that constant worry about safety during sudden stops. The SHARLOVY XL Truck Back Seat Extender for Dogs is designed as a hard-bottom hammock-style back seat cover that extends the usable “flat” area for your pet, while also protecting the upholstery underneath.
On paper, it’s built around one clear idea: add more stable, dog-friendly space without turning your truck into a wrestling match every time you go out. It also leans into safety and practicality, with straps/anchors and provisions for ventilation and easy access.
What it is (and why the hard bottom matters)
This is a large universal back seat cover for dogs aimed at trucks and large SUVs. The standout feature is the hard-bottom design, which the brand says adds nearly 40% extra flat space by extending the rear seating area. It also includes foldable components intended to help you set up a more comfortable “dog bed” feel.

The hard boards plus the hammock layout should, in theory, give your dog a more stable surface than a fully soft cover—useful if your pet tends to shift position when braking or cornering. You also get side flaps that act as buffers, which can help keep your dog from sliding toward the edges when the driving gets a little more lively.
That said, it’s worth bearing in mind that “universal” still means you should check sizing and how your particular truck’s rear seat and seat belt positions line up. A cover can be well designed, but fit is always the bit you need to verify before committing.
Where it shines day to day
A few features are clearly aimed at real ownership, not just display:


- 7-layered construction: the materials listed include 600D scratch-resistant Oxford cloth, waterproof fabric, reinforced hard bottom boards, 35D soft sponge, and cotton layers. The mix suggests a focus on scratch resistance and comfort, while keeping the base more structured.
- Waterproofing and protection: it’s intended to shield your truck seats from mess and damage, which is exactly what you want if your dog tracks mud or carries damp fur after walks.
- Non-slip feel: there’s mention of a non-slip surface, which is important for comfort and for reducing the “scramble” effect when your dog settles.
- Ventilation and visibility: a mesh design is included, which should help airflow and make it easier for you to keep an eye on your pet.

A quick practical scenario
For example: you stop at a muddy country lane, wipe paws as best you can, and drive home. With a waterproof, scratch-resistant hammock back seat cover, you’re not relying on your car seat fabric to survive that trip. Your dog gets a more stable place to lie down (thanks to the hard bottom), and you can then clean the cover with a damp cloth, vacuum, or machine wash depending on what you’ve got on hand.
Key features for safety and control
This cover is fairly confident about safety. It includes six adjustable straps, two safety anchors, and a car seat belt harness for comprehensive protection, plus the side-flap buffering to help secure your pet during stops.
There’s also an extra-high door flap described as helping prevent scratches, alongside the idea that it lets dogs enter and exit without hassle. If your dog is the type that insists on climbing in immediately, that door-flap concept can make life less stressful—though it won’t completely eliminate movement if your dog is particularly energetic.

Installation, cleaning, and versatility
Installation is described as convenient, using buckles and zippers, rather than anything that sounds overly technical. Maintenance is also straightforward: you can clean it with a damp cloth, vacuum, or machine wash.
It’s also pitched as more versatile than a simple seat cover—listed uses include acting as a cargo liner or camping gear. That can matter if you’re shopping for one “all-purpose” protection solution, not a one-trick dog cover.


Still, the way you clean it in practice will depend on how muddy things get and how often you travel with wet dogs. If you regularly get heavy grime, it’s worth planning for a bit of ongoing cleaning rather than expecting one wipe to do everything.
What to check before buying

Because the product is marketed as universal (and specifically for large trucks), it’s smart to verify a few purchase-critical points first:
- Dimensions: the cover measures 70.1 x 59.7 inches, so compare that with your rear bench area.
- Seat belt and anchoring points: the harness and anchors will only help if they can route/attach sensibly in your vehicle.
- How your dog behaves: a hard-bottom hammock is built for stability, but if your dog is very excitable during entry, you may still need to manage them until they settle.
If your priority is a tight, factory-like fit with no gaps at all, “universal” may leave you less satisfied than a vehicle-specific solution. If your priority is protection and extra flat space for larger dogs, it’s more likely to make sense.
Is it worth it?
Buy the SHARLOVY XL Truck Back Seat Extender for Dogs if you want a large, waterproof back seat cover with a hard-bottom extender concept, plus straps/anchors and a seat belt harness approach to safety. It’s a sensible choice for families with larger dogs on longer drives, or anyone who spends a lot of time in pickups and large SUVs where rear seat fabric takes the hit.

Skip it (or at least double-check fit) if your rear seat layout makes it difficult to use the anchoring system and car seat belt harness, or if you need an ultra-tight fit rather than a universal one. Also, if your dog is extremely restless during travel, the added stability helps, but it may not fully replace good training and settling time.
