I used Trapo too. Normally I'll put on top the original mat. sometime you know if any water spill on the edge at least it will not go direct to floor pan. as the secondary original mat will get wet so you can easily wash the original mat rather than it wet the floor pan.

I like Trapo because the bottom part does come with Velcro that can stick on top your original mat.
