Good mats protect the interior, make cleaning easier after hikes or rainy commutes, and help keep resale value. Below I walk you through what really matters when choosing durable mats for an R1S and share a few real-world notes so you can decide with confidence.
Fit & compatibility: why custom-fit matters
R1S is a three-row SUV with tall footwells and a large cargo area, so coverage matters. Custom-fit mats that follow the vehicle’s contours and use the OEM-style anchors will stay put and protect seams and seat rails better than generic ones. Rivian sells its own all-weather set designed for the R1S (good example of OEM fit and anchors).
If you pick universal mats, expect trimming and check that anchors or retention clips line up otherwise mats can shift, especially in the driver’s footwell, which is a safety issue.
Material choices and what they mean for durability
Materials determine cleanup, lifespan, comfort, and smell. Here are the common types and the practical trade-offs:
Thermoplastic Elastomer (TPE) / TPE liners — a popular modern choice. TPE combines many of rubber’s protective properties with better temperature stability and less cracking over time. It’s waterproof, cleans easily, and usually has molded channels to trap water and dirt. Many custom Rivian liners are TPE-based.
Rubber — very durable and waterproof but can harden, yellow, or become brittle over many years depending on formulation. Good for heavy use but sometimes heavier and smellier when new.
EVA/XPE foam — lightweight and comfortable. These are easier on feet but can compress or trap dirt and odors over time; better for light-duty use.
Carpet (nylon/polypropylene) with rubber backing — looks nicer and is quieter, but stains more easily and is harder to deep-clean. Consider hybrid designs (rubber border + carpet center) if you want some style plus protection.
Construction features that actually add lifespan
When reading listings, look beyond the marketing terms. Durable mats have:
- Deep channels and raised edges to hold water, mud, and snow.
- A high perimeter lip so liquids don’t spill onto the carpet.
- A textured walking surface and reinforced driver heel area to prevent wear.
- Secure anchor points or anti-slip backing to stop shifting.
- Good temperature and chemical resistance (so road salts and cleaners don’t degrade the mat).
These features slow wear and keep the mat functional much longer.
Measuring & checking fit before buying
Don’t guess. Measure key spots: driver footwell width/depth, passenger front, second/third row widths, and cargo area. Note where the factory anchor points are and any bumps near pedals. When shopping, prefer vendors that show the 2025 Rivian R1S Floor Mats installed photos or give trim templates. If you must buy a universal mat, mark and trim carefully — better to under-trim and test than to cut too much.
Installation, removal and everyday practicality
I like mats that are easy to lift out, hose down, and refit without fighting clips. Rigid liners (some TPE or rubber) sometimes need a little muscle to remove but are easiest to clean with water. Foldable mats (EVA, thin carpet) are easier to stow but aren’t as protective for serious wet/muddy use.
Cleaning and maintenance tips
For heavy messes: remove the mat, hose it, scrub with a soft brush and mild soap, then air-dry. For carpets, vacuum first and use a carpet cleaner only when needed. Avoid harsh chemicals that can break down polymers — check manufacturer guidance. Always dry mats fully before re-installing to avoid mold or odors.
How to spot durable vs poor-quality mats
Durability indicators:
- Material thickness and consistent edge molding.
- Reinforced driver area and well-placed anchor holes.
- UV and chemical resistance claims (with spec or test data if provided).
- Longer warranty and clear return policy.
Red flags: thin, flimsy feeling material, missing anchor cutouts, or reviews that repeatedly mention fit and slippage.
Safety checks (non-negotiable)
Driver’s mat must never interfere with pedal travel. Make sure mat edges don’t tuck under the accelerator or get lifted by the pedal. If a mat is loose or shifts, trim it, add properly placed anchors, or choose a different design.
A quick note on brands
There are several aftermarket makers that produce Rivian R1S Floor Mats: For example, LASFIT offers TPE custom-fit mats marketed for the R1S and other models; they use elastic TPE and odor-resistant finishes. It is useful to know buyers reviews so you judge based on photos and recent reviews rather than advertising alone. I mention this only so you can compare real-user feedback when deciding.
Durability tests and what to ask sellers
If the listing gives technical specs, look for shore hardness (resistance), UV resistance, and material composition (TPE vs generic rubber). If specs are absent, rely on long-term user photos and warranty length. A 2–3 year warranty is common; longer coverage suggests confidence from the maker.
Eco, comfort and off-gassing
If you care about VOCs or odor, look for low-odor or certified materials (some TPE products advertise non-toxic/low-VOC formulations). Carpet mats are usually quieter and more comfortable, but trade durability for style. Balance what matters most for your driving habits.
Budget guidance
Expect three tiers: budget universal mats (least expensive, may need trimming), mid-range custom aftermarket (better fit and materials), and premium OEM or top-brand liners (best fit, higher price). For an R1S you use for adventures, I’d prioritize fit and edge height over saving a small amount — it’s where damage occurs.
Final thoughts
If I drove the R1S and hiked, biked, or had pets often, I’d go with a well-reviewed custom TPE or premium rubber liner set with good anchors and a cargo liner for the hatch. If I primarily wanted a quieter interior and occasional protection, a hybrid (carpet center with rubber border) would suit me better.
If you’re mostly outdoors/adventure-oriented, prioritize waterproof, heavy-duty liners. If you want a nicer look and only light protection, carpet or hybrid mats may be fine. This helps narrow material and budget choices right away.
