The LinerX Difference

 
   

Most Floor Mats Suck.

Let’s be real. They leave gaps, slide around, and barely protect your car from the messes of daily life. You didn’t buy an awesome car just to let it get wrecked by muddy shoes, pet drool, and spilled snacks. Your car deserves better. You deserve better. That’s why our mats are built for a perfect fit, serious durability, and all-around protection so you can keep your car looking great no matter what life throws at it.

3D Scanning

 

We start with the bare vehicle floor and capture its unique dimensions in 3D, including hard-to-reach corners, raised sections, and factory mounting points.

Engineered to Fit

 

The 3D data is transformed into a vehicle-specific design. Multiple prototypes are evaluated and adjusted until the shape, coverage, and positioning meet our standards.

Built for Your Car

 

After the final fit is approved, the design moves into production—creating durable all-weather liners shaped specifically for your vehicle.
