Here are the back seat covers. I'm not as happy with these as there is a gap between the top and the bottom, so stuff can possibly get in between the seats. A lot harder to put on as well.
I bought the PolyCotton SeatSavers from Covercraft.
They are not super pretty, but very functional for my needs. I haven't put the back ones on yet, but plan on doing that this week if someone wants to see that pic. Front seats are two pieces. One for the seat and a separate cover for the headrest.
I go to the beach a lot and I bring a 64oz Hydro Flask bottle... I needed something to keep it from rolling around on my seat, so I decided to make a "cup" holder for it!
