Highlighted Features

100% Custom Fit: cut to order from a template for your exact make, model and year. No trimming, no universal shapes, no curling corners.

Automotive Grade Leather: the top surface is automotive grade leather, waterproof and stain-resistant, and wipes clean.

Diamond Quilted Stitch: the signature diamond pattern runs across the full surface, giving the cabin the look of factory upholstery.

95% Floor Coverage: the mats extend up the sides and around the console, covering far more than factory mats.

All-Season Resistant: built for Quebec winters and Texas summers. Road salt, snow, mud and spills stay on the surface and wipe away.

10mm High-Density Foam Core: comfortable underfoot, holds its shape over years of use.

Anti-Slip Base: a textured base grips the carpet underneath, and built-in anchors snap onto your factory clips, so the mat does not slide or bunch.

Easy To Clean: damp microfiber cloth and mild soap. No vacuuming, no shampooing, no drying time.

Quick Installation: remove your existing mats, slide the Matrikar set in, align with the factory anchor points. No drilling, no tools, no modifications. Full install in under five minutes.
