I got the Smittybuilt Neoprene (black/grey) covers (S/B47222) for front seats and rear bench.
Had them installed about 1,5 year ago.
They fitted easy over the original seats and bench, snug fit by the laces.
I use the car for fun drives around town and A LOT for off-road wheeling.
Don't know if the seats get dirtier from the mud and sand while being off-road or from the dirty tools that are tossed on them while working on the car.
They suppose to come off easy for cleaning but I havent had them removed in all those times, just clean them with a wet cloth and let them dry in the sun.
I think they still look like new.
Can recommend them.
Ow, I got a deal with 4wd.com; free rear seat when buying the front seats.
