Full length Cargo Mat

I'm looking for a "roll out" cargo mat for when both seats are folded down.
Any ideas??
Thanks

I've seen two full length cargo mats that are not roll out, but instead stay on whether the rear seats are up or down.

Sigma Automotive sells this very nice looking one for $225 (but note that because of the material, it bunches/curls when the rear seats are up):

And Autoanything sells this canvas one made by Canvasback for $149 (picture below is not of the Prius; but they make it for the Prius -- click on the link below):

Canvasback SUV Cargo Liner, Canvas Jacket Liner

Thanks

I just ordered one of these:

I read the reviews, and the only negative was that it can be a bit slippery for the dog. Has a split for the seats, with a zipper to close when they are both down.

They are on sale ($10 off) for another week, AND if you use the coupon code SAVEFIVE you will get an additional $5 off. I'll report back when I get mine!

(oops; just realized I can't yet post a link. The product is the Canvasback cargo liner, site is hunterk9 dot com)

I use the cargo liner from a 4Runner. This keeps the rear very clean - from dogs, my bicycle, recycling bags, etc. Easy to clean and keep clean.
