Just catching up on this thread and wanted to chime in from a safety perspective. Ive always been super paranoid about mats sliding around and interfering with the pedals, especially in a big SUV like the QX80. Honestly, I initially tried some generic ones and had a close call when the mat shifted under the brake during a sudden stop. After that, I stuck with the Infiniti QX80 OEM All-Season Floor Mats High Wall. They utilize the factory locking pins perfectly, so they wont budge an inch, which is huge for peace of mind. If you want something more rugged, the WeatherTech FloorLiner HP Custom Fit Mats are great because the HP material is grippier than their standard versions, though they can still feel a bit industrial. Another solid choice for safety is the 3D MAXpider Kagu Series All-Weather Floor Mats because that backing literally grips the carpet like velcro. Just make sure whatever you pick doesnt block the rear floor vents under the captain's chairs.

Just saw this, but SMARTLINER All Weather Custom Fit Floor Mats for Infiniti QX80 are a solid bet to save cash. Theyre reliable and keep mud contained without costing a fortune, honestly... basically dont overpay.

Saving this whole thread. So much good info here you guys are awesome.

I've spent way too much time looking at fitment specs, and honestly, the TuxMat Custom Fit Floor Mats for Infiniti QX80 are the winner for the Autograph trim. Their three-layer design uses an EVA foam core for sound dampening and a PVC top layer that handles winter slush better than basic TPE. The wall height is way higher than WeatherTech FloorLiner HP, basically sealing the gaps near your second-row console.

Personally, if you're looking for that premium feel without the stiff plastic vibe, I'd check out the Husky Liners X-act Contour Floor Mats for Infiniti QX80. The main technical difference is the material—they use a rubberized thermoplastic instead of the rigid stuff. This means they stay flexible in freezing temps and don't curl at the edges over time. For the Autograph setup, you really need that precise fit around the second-row console. The Husky liners have these stay-put cleats on the bottom that actually work, so the mats wont slide around when kids are jumping in and out. Another solid choice is the WeatherTech FloorLiner HP High Wall Mats. They're technically advanced with a laser-measured fit, though they can feel a bit more industrial. Both options offer the high-wall protection you need for winter mud and are way easier to spray down than the factory carpet ones.
