Been a big fan of this one, used it in two Tiguans. It has some holds that slide between the seat and the back rest that hold it down well, and it's just the right width. https://www.amazon.com/gp/product/B013VPZTAQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

We use one of these for the back seat and a console cover also in both our Forester and Crosstrek. The back seat cover works in both vehicles. Our Black Lab likes to come up to the front seats while driving so we found that raising the console to full open keeps him back there.
