Hi all, does anyone have (or can measure for me) the dimensions of the seat itself? I've seen the specs of headroom and hip room and such, but that's not what I need. I'm looking to get the actual seat dimensions. Here is what I am specifically looking for: The width where your butt bone sits (back of seat) from left to right, the width of the seat at the mid point from left to right, and the length of the seat from butt bone forward to the front edge. With that, I want to see if the seat is basically the same size as in a grand cherokee, or if the seat is overall bigger/wider in all directions or certain directions. Thanks!
