If you’re hunting for the best floor mats for a Rivian R1S, you’re really trying to protect one of the nicest EV cabins on the market. Between muddy trailheads, kids, pets, and winter slush, the wrong mats can leave your R1S stained, smelly, and harder to sell later, especially as more used Rivians start hitting the market.
Quick Take
Why Floor Mats Matter So Much on a Rivian R1S
Rivian didn’t build the R1S to be a mall cruiser. Owners use these SUVs for snow days, camping trips, mountain bikes, dogs, and messy kids. That’s exactly the kind of lifestyle that destroys light-colored carpet if you don’t protect it early. Good floor mats do three things at once: they keep the cabin looking new, make cleaning easier, and protect your Rivian’s resale value if you ever decide to trade it in or sell it.

OEM vs. Aftermarket: Which Rivian R1S Floor Mats Are Best?
OEM Rivian All‑Weather Mats
- Pros: Designed by Rivian for the R1S, with factory‑matched anchors and trim lines. Fit and coverage are usually excellent for the specific generation they’re made for.
- Cons: Coverage isn’t always "full tub" style, so some carpet can still show at the edges and under the pedals. They tend to cost more than many aftermarket sets.
- Best for: Owners who prioritize factory look, branding, and plug‑and‑play fitment.
Aftermarket Floor Liners
- Pros: More options for full‑coverage raised edges, deeper channels for snow and mud, and often lower prices. New players like Lasfit and LinerX now offer R1S‑specific sets.
- Cons: Fit can be hit‑or‑miss, especially early in a model’s life cycle or after a refresh. You may need to stretch or adjust to snap into Rivian’s anchors.
- Best for: Drivers who use their R1S hard off‑road or in winter and want maximum coverage above all else.
Watch for Generic Fit Claims
Gen 1 vs. Gen 2 R1S: Fitment Traps to Avoid
By late 2024 and into 2025, Rivian started referring to refreshed vehicles as Gen 2. That matters for floor mats because the driver footwell and anchor locations aren’t identical to earlier builds. Owners have already reported situations where older all‑weather mats were sold for Gen 2 trucks, only to find the driver’s mat riding on a small floor bump and interfering with the accelerator pedal.
Safety First: Pedal Interference
- Always match mats to your exact model year and confirm they’re labeled for Gen 1 or Gen 2 as appropriate.
- If you bought Rivian OEM all‑weather mats, verify that the box and product page show compatibility with your generation before installation.
- Avoid "close enough" fits or trimming around the accelerator, on an EV with instant torque, that’s not a corner worth cutting.
- If the grommets don’t line up with the carpet snaps, don’t force it. Either the mat or the anchors are wrong for your build.
Top Rivian R1S Floor Mat Options in 2025
There’s no single "best" Rivian R1S floor mat for every owner, but a few patterns are emerging. Here’s how the main choices shake out based on coverage, material, and how you actually use the truck.
Rivian R1S Floor Mat Options at a Glance
Match coverage and material to how you really drive
1. OEM Rivian All‑Weather Mats
Best for: Owners who want factory look and zero guesswork on anchors.
- Rubber composite construction with Rivian branding.
- Generally excellent alignment with factory floor snaps.
- Coverage is good, but not as extreme as some full‑tub aftermarket liners.
- Watch compatibility notes: many early sets are marked "Gen 1 only."
2. Premium Aftermarket Liners
Best for: Heavy winter use, off‑road, kids and dogs.
- TPE or similar flexible thermoplastics with high sidewalls.
- Deep channels to trap mud, sand, and melted snow.
- Options for matched cargo and seatback liners to protect when seats are folded.
- Examples include dedicated R1S sets from accessory specialists and newer brands focused on full coverage.
3. Carpet & Designer Mats
Best for: Mild climates, mostly on‑road use, or owners who want a more "living room" feel.
- Carpeted mats and designer weaves (including Rivian‑inspired Chilewich styles).
- Less ideal for heavy mud or snow but nicer underfoot and quieter.
- Useful as a second set you swap in for summer or urban driving.
Coverage & Use-Case Comparison for R1S Floor Mat Types
Use this matrix to narrow down which style best fits how you use your Rivian R1S.
| Mat Type | Coverage | Best For | Weakness |
|---|---|---|---|
| OEM All-Weather | High (not always full tub) | Balanced daily use, moderate weather | Can leave small exposed carpet areas; Gen 1 vs Gen 2 compatibility matters |
| Premium Aftermarket TPE | Very high (raised edges, deep channels) | Snow belts, dirt roads, kids, pets | Fit quality varies by brand; may require some stretching to snap in |
| Carpet / Designer | Medium | Mild climates, city driving, quieter cabins | Holds stains and odors more easily; not ideal for heavy mud |
| Cargo & Seatback Liners | Very high in cargo area | Camping, dogs, home‑improvement runs | Some designs can bunch when seats move; check compatibility with 3rd row |
"Best" depends on where and how you drive, plus who rides with you.

How to Choose the Best R1S Floor Mats for Your Use Case
Key Questions Before You Buy Rivian R1S Floor Mats
1. What’s your climate and terrain?
Snow, road salt, and red clay demand aggressive channels and high sidewalls. If you’re in Arizona or Southern California, you may prioritize heat‑resistant, low‑odor materials over snow performance.
2. How messy are your passengers?
Kids, pets, and frequent car‑camping justify full sets including 3rd‑row and cargo liners. If it’s usually just you and a front passenger, you might skip rear coverage, though you’ll pay for that later when you sell.
3. Do you own a Gen 1 or Gen 2 R1S?
This is non‑negotiable. Match mat generation to your vehicle generation. Don’t assume a Gen 1 mat will be "close enough" in a Gen 2, especially on the driver’s side.
4. Do you prefer a factory look or maximum protection?
OEM mats tend to look the most integrated, but some aftermarket designs protect more of the door sills and carpet edges. Decide which matters more to you up front.
5. Do you need cargo and frunk protection too?
If you haul bikes, camping gear, or home‑improvement supplies, add a cargo liner and, ideally, a frunk mat. That keeps mud and sharp edges off your trim and wiring access panels.
6. How long do you plan to keep the R1S?
Short‑term lessees might live with lighter coverage. Long‑term owners and anyone thinking about resale should protect every high‑traffic surface from day one.
Installation & Safety Checklist
Even the best Rivian R1S floor mats can cause problems if they’re installed wrong. Here’s a quick process to follow every time you swap or upgrade mats.
Safe Installation Steps for Rivian R1S Floor Mats
1. Remove any existing mats first
Never stack mats. Layering an all‑weather liner over the stock carpet mat raises the pedal area and makes it easier for the accelerator to catch the edge.
2. Align with factory anchors
Rivian uses floor snaps/grommets to keep mats from sliding. Line up the grommets on your new mat, then press firmly, sometimes you’ll need a solid push or even a rubber mallet to fully engage them.
3. Check around the accelerator and brake
Verify that no mat edge rides up on the floor bump in front of the accelerator or behind the brake. If the mat doesn’t sit flush on its own, it’s the wrong part for your build.
4. Do a pedal sweep test
While parked, move your right foot from rest to full throttle and full brake several times. Make sure nothing snags or feels spongy. Repeat with different shoes, including boots if you wear them.
5. Verify second- and third-row movement
Slide and fold rear seats through their full range. The mat should flex but not bunch, hang up on rails, or pull loose from its anchors.
6. Re‑check after the first week
After a few drives, inspect for creeping, curling edges, or interference with pedals and seat tracks. Re‑seat or replace as needed.
When to Return a Mat Set Immediately
How to Clean and Care for Rivian R1S Floor Mats
Good mats are only half the story. Keeping them clean makes your R1S feel newer, and it prevents grit from acting like sandpaper on your interior plastics and carpet.
- Shake and vacuum regularly. Pop mats out and shake them once a week if you’re in dusty or sandy areas. A quick vacuum keeps grit from building up in channels.
- Rinse with low‑pressure water. For all‑weather liners, a garden hose is usually enough. High‑pressure washers can strip surface oils and leave some rubber or TPE mats looking permanently chalky.
- Use mild cleaners, not harsh solvents. A bit of car‑wash soap in a bucket is fine. Avoid strong degreasers or household chemicals that can dry out or discolor the material.
- Let them dry completely before reinstalling. Trapping water between a mat and the carpet is a recipe for odor and mildew, especially in humid climates.
- Inspect edges and grommets as you clean. Catch early signs of curling, cracking, or broken anchors before they become a safety or resale problem.
Pro Tip: Skip the Shiny Dressings
How Floor Mats Affect Used Rivian R1S Resale Value
Floor mats sound like a small detail, but in the used EV market they’re one of the first things buyers (and appraisers) notice. Clean, protected carpeting tells a story: this Rivian was cared for. Stained footwells and a trashed cargo area suggest years of neglect, even if the battery and electronics are in great shape.
From a Buyer’s Perspective
When you walk up to a used R1S and see heavy wear on the driver’s heel area, rock chips embedded in the cargo carpet, or dried coffee stains under the second row, you immediately start discounting your offer. You’re also wondering what else wasn’t maintained.
By contrast, clean mats and carpets reinforce the idea that the owner cared about everything, tires, software updates, and battery health included.
What This Means at Trade‑In
On a platform like Recharged, we look at interior condition right alongside battery health and service history. A well‑protected cabin can help your R1S stand out from other used listings with similar mileage.
If you’re shopping instead of selling, that same logic works in your favor. A used R1S that already has quality floor liners and a documented care history is a strong signal you’re looking at a well‑kept EV.
