Tacoma Seat covers?

I've been looking at getting seat covers for my '07 double cab Taco. I've found that Toyota parts store offers them just for the front. Who has these and how do you like them? Also, I'm a bit ignorant but what's the difference between offroad and not offroad from seats covers? These seat covers are on sale for $160 right now. I would have them already if they offered a back seat cover.

Then there's Wet Okole seat covers? I see a couple on this forum use these. How do you like them? I like the fact that they will make them for front and back of a double cab. However, for $259 for the front and $259 for the rear seems a bit steep? Are the worth buckin' up for these with the addition of getting a back seat cover also?

Thanks,
Boks
