First, you have to do the easiest part, which i found to be the hardest, because all the other write up's left out the part in which they tell you to push the button forward and not down.
Refer to these two videos on how to remove the ass cushion portion of the seat.
This first video shows the button mechanism and how to push it.
Believe me, this video will definately help you understand how to push the button. I must have spent 20 minutes trying to figure out how to push this damn thing right because i was pushing it down towards the floor.
and here is where it is located under the seat. There is one under the middle part of the drivers side rear seat and the other under the middle of the passenger side rear seat. Yes, that's me.
so anyways, once you push the button on one side, you lift it up a little bit, then go to the other side and push that button and lift. The seat should lift right off. Remove the seat from the car, and you should see something like this.
now, look under backrest portion of the rear seat near the middle. There should be two 10 mm bolts near the middle of where both the left and right rear seat should meet, one bolt on the side of each rear seat nearest to the middle. Remove them with a 10 mm socket.
now, fold down the rear seats and go back up to the top of the rear seats. Remove the head rest panel via these three bolts, one on each side and one in the middle. Note that only one is pictured in the first picture, and the other one is on the opposite side.
after you remove them, it should come right off.
Now, you should see these bolts. Remove all of them with one of those screwdrivers with the interchangeable tip removed. I don't remember the size, but you'll figure it out
after you remove them, note that it doesn't immediately drop the rear seat bracket. The area where the trunk carpet is connected to the rear seat backrest bracket is holding it via plastic tabs.
An easy way to remove these tabs is by prying it off with one of these things. The pictures are self explanatory
After you have removed these two or three tabs, you can remove the carpet from the seat bracket and take out the backrest and bracket connected to it.
WATCH OUT!! there are exposed metal parts of the bracket that can and will scratch you and your interior up.
30 minutes after i was done i noticed two or three areas on me where i was scratched up and was bleeding, and i didn't even notice it till i saw the dried up blood.
Now that you've removed your rear seats, you will have something that looks like this. Get a rear seat delete if the excessive noise and things from your trunk flying at your face during braking annoy you, or just don't put anything in your trunk and deal with it like i am doing (for now)
