Warning: the rear-seats are a pain. I'm a newb to seat covers, but wanted to keep the cloth clean so I purchased a cheap one off Amazon that came as a set for the front bucket and rear bench seats.
The rear bench doesn't slide the seat belts in through a slit at the rear of the cushion: they are fed through a hole in the bench seat cushion. You have two holes to feed your belt buckles through: one hole will have one buckle, the other hole will have two buckles. The hole with two buckles is a royal pain to do. This two-buckle hole is only big enough to fit ONE buckle through comfortablely. I somehow got it shoved through but was seriously sweating at the end due to the odd angle of working in the back.
To add insult to injury, the rear bench seats are concave such that the rear covers stretch above the actual seat cushion so it looks like there's two trampolines where a seat would be. I kid you not, I tossed my lunch bag in through the driver's side rear door and it BOUNCED from one trampoline to the next, bouncing AGAIN and smacking into the passenger's side rear door. I was so thankful I had a sandwich wrap and not something less robust packed for lunch.
Front seats are a piece of cake. Really helps to manually jack the seat up. If you have the heated seats, mind catching the power cables on the seat cover buckles so the power cables don't rub on anything.
