I've got an 08 Hylander, so I was a little concerned about the size of the cover.  After measuring my back seat multiple times, I concluded that the cover would fit, but it would be tight.  Turns out it's about 4 inches short, about 2 inches on each side.  Not the end of the world, I can live with a couple of inches of seat uncovered.  Cause my dog isn't going to hit those exposed inches on either side of the cover.
