The best cargo liners
The trunk is the one part of a car interior designed to get dirty, and the only one most people leave unprotected. A liner turns the floor into a tray.

The short answer
Buy the WeatherTech cargo liner if you carry things that leak, and a cheap universal mat if you do not. The molded liner is custom-cut per vehicle, made from TPE with no PVC or phthalates, publishes FMVSS302 flammability compliance, and has a raised outside lip that turns the trunk floor into a shallow tray. That lip is the whole product: it is the difference between containing a spill and redistributing it into the spare wheel well.

The raised lip is the entire argument
A flat mat protects the carpet it covers. A liner with a raised edge protects the carpet it covers and everything the spill would otherwise have run to.
That matters more in a trunk than anywhere else in the car, because a trunk floor is not flat. Underneath it is the spare wheel well, the jack, the tool tray, and on many cars a wiring loom and the fuel tank sender access. A gallon of anything that gets past a flat mat goes into a void you cannot easily reach, dry or clean.
Custom-molded versus universal, honestly
Custom-molded means the liner is designed from a scan of that specific vehicle's cargo area, including the wheel arch intrusions, the seat-back angle and the sill. Universal means a rectangle you trim.
The custom fit genuinely matters for the lip. A trimmed universal mat has cut edges that no longer turn up, so at the exact places where the shape is complicated — the wheel arches, the sill lip — the containment is gone. Those are also the low points that liquid finds.
The counter-argument is real too: a vehicle-specific liner is worthless when you change cars, and it costs several times what a universal mat does. If you carry dry things and want the carpet to stay clean, a universal mat does that for a fraction of the money.
| WeatherTech cargo liner | Universal mat, typical | |
|---|---|---|
| Fit | Custom molded per vehicle | Trim to fit |
| Material | Custom blended TPE | Usually not specified |
| Raised lip | Yes, molded | Lost at any trimmed edge |
| Published standard | FMVSS302 | None |
| Material content | No PVC, phthalates, BPA, cadmium, lead | Not published |
| Recyclable | 100% | Not published |
What FMVSS302 actually is
It is the US federal standard for the flammability of interior materials in vehicles. It specifies a horizontal burn test and a maximum burn rate for anything used as an interior component.
This is worth explaining because it sounds more dramatic than it is. FMVSS302 is not a claim that the liner is fireproof; it is a claim that it behaves the way a factory interior component is required to behave rather than substantially worse. Original equipment carpet meets it. A generic rubber mat of unknown composition may or may not.
Nobody buys a cargo liner because of a flammability standard. It matters here because it is one of the very few published, named, third-party standards anywhere in the car accessory world, and a maker that cites one is a maker that has tested something.
TPE, and why the material matters in a hot car
Thermoplastic elastomer is the material WeatherTech uses across its liners. Three properties matter for a trunk.
- It stays pliable across a wide temperature range. A trunk in a parked car reaches the same 60-70 C as the cabin, and a material that softens becomes floppy and loses its lip
- It is virtually odorless. Cheap PVC mats in a hot sealed trunk produce a smell that gets into everything — which is its own problem, covered in how to get smells out of your car
- It contains no PVC, phthalates, BPA, cadmium or lead, which WeatherTech publishes explicitly, and it is fully recyclable
A liner does not stop things moving
Worth stating plainly, because the skid-resistant surface claim leads people to expect more than it delivers. A textured surface stops a box creeping under gentle acceleration. It does nothing under hard braking, and nothing at all in a collision.
Anything heavy in a cargo area needs restraint, not friction. A cargo net or a set of tie-downs is the answer, and it is cheap — see best cargo nets and tie-downs. A rigid organizer with securing straps does the same job with structure, covered in best trunk organizers.
Who should buy which
Buy the molded liner if you regularly carry anything wet, dirty or leaking: a dog, garden waste, sports kit, camping gear, groceries in a car with no bags. It is also the right answer if you carry a dog in the cargo area rather than on the seat, which we cover in best dog car seat covers.
Buy a universal mat if the trunk carries shopping and a bag, you change cars often, or the car is a lease you will hand back. The carpet stays clean either way; you are paying the difference for containment you may never need.
And if the floor of the car proper is the problem rather than the trunk, that is a different product — see best all-weather floor mats and all-weather mats vs carpet.
Every pick, with the working
Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up. Rows that read “Not published” are not omissions on our side: they are things the maker will not commit to in writing, and they cost the product points on the transparency axis.

Our pickA trunk that carries things that leak
WeatherTech Cargo/Trunk Liner
Custom-molded per vehicle in the same TPE as the floor liners, with a raised lip that turns the trunk floor into a tray. It publishes a flammability standard, which nothing else in this category does.
- Material
- Custom blended thermoplastic elastomer (TPE)
- Fit
- Custom molded per vehicle
- Edge
- Raised outside lip to contain spills
- Surface
- Skid-resistant
- Standard met
- FMVSS302
- Material content
- No PVC, phthalates, BPA, cadmium or lead; 100% recyclable
- Manufacture
- USA
- Warranty
- Not published
- List price
- Not published
What it gets right
- Custom molded to the specific vehicle rather than trimmed to fit, so the raised lip actually seals the floor
- Meets FMVSS302 flammability standard — a published, named standard in a category with none
- TPE with no PVC, phthalates, BPA, cadmium or lead, and 100% recyclable
- Designed, engineered and manufactured in the USA on American-made tooling
Flaws
- Vehicle-specific, so it is worthless if you change cars
- The raised lip is a containment lip, not a wall — a gallon of anything will still find the edge
- The most expensive way to protect a trunk floor
The working behind the 9.2
- Heat headroom: not scored (weight 22%)
- The maker publishes no operating-temperature ceiling, so this axis is dropped and the other weights are re-normalized.
- Install effort: 10.0 (weight 24%)
- Drops in and sits there. No fixing of any kind, and it comes out again when you sell the car.
- Price against the ceiling: not scored (weight 24%)
- No published list price we could cite on the compile date, so this axis is dropped and the other weights are re-normalized.
- Written commitment: not scored (weight 15%)
- No warranty term published, so this axis is dropped and the other weights are re-normalized.
- Spec transparency: 7.8 (weight 15%)
- 7 of the 9 specifications we went looking for are published by the maker (78%). A blank row is never a guess here: it prints “Not published” and it costs the product points, because a figure nobody will commit to in writing is a figure you cannot check.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled September 4, 2026 from WeatherTech Cargo Liner published specifications.
2The published-material benchmark
WeatherTech FloorLiner HP
A 3.2 mm multi-layer TPE compound at 62 Shore A hardness, laser measured to the vehicle. WeatherTech is the only maker in this category that publishes a thickness and a durometer figure, and that is why it is the benchmark: everyone else says tough and WeatherTech says 62 Shore A, which is a number you can hold them to.
- Thickness
- 3.2 mm
- Hardness
- 62 Shore A
- Material
- Multi-layer TPE compound
- Fit method
- Laser measured per year, make and model
- List price
- Not published
- Warranty
- Not published
What it gets right
- Publishes thickness (3.2 mm) and hardness (62 Shore A), which nobody else does
- Laser measured per year, make and model, so the edges actually go up the footwell walls
- Rigid enough to hold a raised lip, which is what contains a spilled drink
- Sold direct with a vehicle fitment tool, so ordering the wrong one takes effort
Flaws
- Sold direct by WeatherTech and fitted by vehicle, so it is not a click-and-forget purchase
- The rigidity that makes it hold shape also makes it fiddly to get in and out for cleaning
- The most expensive option in this category by a clear margin
The working behind the 8.7
- Heat headroom: not scored (weight 22%)
- The maker publishes no operating-temperature ceiling, so this axis is dropped and the other weights are re-normalized.
- Install effort: 10.0 (weight 24%)
- Drops in and sits there. No fixing of any kind, and it comes out again when you sell the car.
- Price against the ceiling: not scored (weight 24%)
- No published list price we could cite on the compile date, so this axis is dropped and the other weights are re-normalized.
- Written commitment: not scored (weight 15%)
- No warranty term published, so this axis is dropped and the other weights are re-normalized.
- Spec transparency: 6.7 (weight 15%)
- 4 of the 6 specifications we went looking for are published by the maker (67%). A blank row is never a guess here: it prints “Not published” and it costs the product points, because a figure nobody will commit to in writing is a figure you cannot check.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled September 4, 2026 from WeatherTech FloorLiner HP published material specification.

3Laser-measured fit without the WeatherTech price
Husky Liners WeatherBeater
Skip this one. It is a good floor mat and this is a page about the trunk. The reason it is here is that people routinely buy a set of floor mats expecting the set to include the cargo area, and it does not — the cargo liner is almost always sold separately, and it is the piece that actually earns its money.
Rubberized thermoplastic with Husky's ProGard formula, laser measured to the vehicle like the WeatherTech but more flexible and cheaper. Husky publishes lab-test claims of 78 percent greater durability and 30 percent lower cost against WeatherTech FloorLiner. Those are Husky's own tests on Husky's own blog, which is exactly how much weight to give them.
- Material
- Rubberized thermoplastic, ProGard formula
- Fit method
- Laser measured per year, make and model
- Maker's durability claim
- 78% more durable than WeatherTech FloorLiner
- Independent verification
- Not published
- Thickness
- Not published
- Hardness
- Not published
- List price
- Not published
What it gets right
- Laser measured per vehicle, so the fit argument is not the differentiator it used to be
- More flexible than the WeatherTech, which makes taking it out to hose it down a one-handed job
- Consistently cheaper for the same coverage
Flaws
- The 78 percent durability claim is Husky testing Husky against a competitor, published by Husky
- Husky does not publish a thickness or a durometer figure, so there is nothing to compare against WeatherTech's 3.2 mm and 62 Shore A
- More flexible also means a lower lip that holds less liquid
The working behind the 7.8
- Heat headroom: not scored (weight 22%)
- The maker publishes no operating-temperature ceiling, so this axis is dropped and the other weights are re-normalized.
- Install effort: 10.0 (weight 24%)
- Drops in and sits there. No fixing of any kind, and it comes out again when you sell the car.
- Price against the ceiling: not scored (weight 24%)
- No published list price we could cite on the compile date, so this axis is dropped and the other weights are re-normalized.
- Written commitment: not scored (weight 15%)
- No warranty term published, so this axis is dropped and the other weights are re-normalized.
- Spec transparency: 4.3 (weight 15%)
- 3 of the 7 specifications we went looking for are published by the maker (43%). A blank row is never a guess here: it prints “Not published” and it costs the product points, because a figure nobody will commit to in writing is a figure you cannot check.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled September 4, 2026 from Husky Liners WeatherBeater product page.

Questions people actually ask
Do floor mat sets include a cargo liner?
Almost never. A front-and-rear mat set covers the passenger footwells; the cargo area is sold separately as its own piece. This is the single most common surprise when buying mats.
Will a cargo liner fit if I fold the rear seats down?
A cargo liner is molded for the cargo area with the seats up. Folding the seats creates a larger, differently-shaped space the liner does not cover. Some makers sell an extended or seat-back piece separately for exactly this.
Is TPE better than rubber?
For this application, generally yes — it stays pliable across a wider temperature range, it is odorless, and it is recyclable. “Rubber” on a listing usually means an unspecified compound, which is the real difference: one is a named material, the other is a word.
Can I cut a universal mat to fit?
You can, and you lose the raised lip everywhere you cut. Since the lip is the reason to buy a liner rather than a mat, a heavily trimmed universal liner is mostly just a mat.
