I bought weathertech for my 09. I'm having the front passenger side replaced, as it curled up and distorted itself in the heat during the summer, so it lost it's "form" but the drivers side and middle row are great, and don't move around. I didn't need to secure them down, they sit just fine. For anyone interested, i have captain chairs for the middle row, and the weathertech fits just fine, although obviously i have a small gap in the middle of the seats.

 

That's odd, I've had my weathertechs for a while without issue. Been through 2 Arizona summers and never had problems with them deforming.

 

I have the Lund mats, finally.
When I get the H2 back torque converter / flex plate install, I'll see how they work out.

So far, they are no slippery to the touch, the like the new weathertechs I have in my H3.
