WeatherTech 4616414IM FloorLiner HP 3rd Row Custom Floor Mat Grey

The WeatherTech 4616414IM FloorLiner HP is a precision-fit, high-performance floor liner engineered for the 3rd row of the Toyota Sienna 8-Passenger. Digitally laser measured to match your vehicle's exact interior dimensions, this custom floor mat delivers complete coverage across the bottom, front, back, and sides of the footwell — going far beyond what a standard floor mat can offer.

Constructed from a proprietary Thermoplastic Elastomer (TPE) compound, the FloorLiner HP strikes the ideal balance between flexibility and durability. Unlike rigid floor liners, the TPE material drapes naturally over the floor contours while maintaining high, standing sidewalls that contain spills, dirt, mud, and debris. The material is engineered to withstand extreme temperatures without cracking, curling, or breaking down, making it a true all-season solution.

Key Features:

• Laser-measured custom fit — precisely contoured to the 3rd row footwell of the Toyota Sienna (8-Passenger)
• Advanced TPE construction — flexible, rubber-like material that is soft to the touch yet highly durable
• High-walled design — covers the floor, front, back, and sides of the footwell for full 3D protection
• Anti-slip retention system — non-slip nibs and a specially designed retention system keep the liner securely in place with no shifting or sliding
• Beveled edge design — prevents sidewalls from curving inward, maintaining structural stability
• Watertight sill — seals around the retention clasps to prevent liquids from migrating onto the underlying carpet
• Eco-friendly materials — 100% recyclable TPE; free of latex, PVC, cadmium, and lead
• Made in the USA — designed, engineered, and manufactured by WeatherTech in America

The FloorLiner HP represents WeatherTech's next generation of floor protection, offering superior coverage compared to traditional floor mats or even the original FloorLiner. It is the ideal upgrade for protecting your Toyota Sienna's interior from daily wear, spills, and the elements — while preserving resale value and keeping your cabin looking its best.
