I thought it could be useful to someone to share this info.
**Disclaimer**
This isn't really a guide, but rather, notes I had made for myself. Also, all of this happened over a year ago and I'm rather deficient in the memory department. So, I could be mistaken about some of the details. Please don't shoot me!

First of all, I purchased a pair of new seat covers from http://interior-innovations.com

Base price - $200
Perforation - $75
Embroidery - $25
Shipping - $25
TOTAL = $325

Not a bad deal for custom ordered, PLEATHER seat covers. Much better than the $1200 quoted me by a local shop. Although, in retrospect, I understand the huge markup for labor.
I think real leather was a few hundred more. But I've been told that synthetic materials will last just as long or even longer than the real stuff. And since this was my first attempt at something like this, a smaller investment is desirable in case of disastrous outcomes.

Ok, I'll skip showing you how to remove the seats from the car and all the plastic trim covering all the mechanical bits. If you can't figure out a few screws and nuts, then I would advise you against attempting to proceed further with this type of project. Although, I will say that one of the adjustment knobs had a cap covering a screw, whereas the other had a clip holding if from underneath...tricky.

Now as I stop rambling and start to actually get to the meat and potatoes of this post, I realize that somewhere between moving and getting a new phone, I've misplaced photos. So, I'll try to explain the process as clearly as I can, and if I am able, update this when I get back stateside.

First of all, with the seats in my secret lair (spare bedroom), I took the seats off the rails, just to make them easier to heft around. With the passenger seat this was no problem. With the driver's side seat, however, as with getting to the nuts to remove the seat from the car, power is required to move the seat back and forth to gain access to the necessary bolts. Back out to the car we go. On a side note, I had a difficult time getting the framework to go back into alignment for the bolts to match up with the rails. So, maybe it's not a good idea to remove them in the first place. But, I wanted to paint mine anyway, because they were quite rusty. And also because of this...discovery...

Image

Then I removed all the plastic coverings. I think there were only 3-4 screws involved in this process.

Then I segregated the back from the bottom of the seat. Pull up on the lever that actuates the seat tilting function. This releases the latch. Now all that's left is to pull the seat back off the hinges. There are clips securing these, which will need to be removed first. Now work the seat back and forth until the two sections separate from each other.

Image

Starting with the seat back, the first thing to do is remove the headrest. This is one of the more difficult tasks of this project. There is a retaining latch on both posts of the headrest. They are located on the outer edges of where the posts set into the seat top. You might need to cut the fabric to gain adequate access to release them. I used a flat screw driver, but I don't remember if I had to press them inward or outward. Also, I have read where people only mentioned having one to deal with. I had two. One on each side. Idk.

With the headrest out of the way, undo the zipper that attaches the top of the back padding to the rest of the seat. The ends will be tucked in and require a little effort to work free. The padding will now bend forward giving you access to the hog rings that secure it around the midsection. Cut through these with some snips.

Image

There are a few more rings securing the bottom as well.

Image

You can get to these easier, as well as, a few others, if you flip the seat back rest over.

Image

You now have a detached foam section. In its midsection again, but on the opposite face, there are some rings holding the fabric and foam together.

Image

Moving on to the main seat back, there are many hog rings to remove. I haven't even labelled them all, but just keep cutting until they are all gone.

Image

Removing the rings holding the black canvas in place, lets you access the actual hog rings that secure the material over the side bolsters.

Image

Now just peel everything off.

Next is the seat bottom. Three of the four bottom edges are secured by hog rings: the front, back, and inside edge. The outer edge is secured by plastic, to give the outside face a clean appearance.

Back

Front
Image

Also, the drivers side will have the power seat controls in the way. The inner two screws were what held the plastic trim on. The outer two screws are what secure this assembly to the seat frame. Once everything is out of the way, the seat cover can be peeled off of the bolsters.

Image

Underneath, remove the rings holding the black "crumb trays" and push them aside.

Image

The material here is simply stapled to the foam cushion. The staples literally disintegrated from being so rusty.

Image

Now on the other side of the black canvas are some more hog rings. Remove on both sides. The material should now be able to pull through the slits to the top side of the seat.

Image

Up top there are two hog rings securing each side. Remove.

Image
Image

With those out of the way, you can maneuver the material to get to the last set of rings in the center. Clip these and the seat cover pulls free!

Image

Now you may think that was all so simple...and you'd be right to think so. The genius of making these notes is in being prepared when the time comes to undertake the far more difficult task of attaching new covers on the old seats.

Also, make sure you have the authorization from the proper authorities before you go cutting into things...

Oh yeah. Now the head rest that was first pulled out... It had a few staples holding the material in place. Pull those out and the cover can be stretched off and the new one stretched on and stapled in place. LOL :tisk: Getting the new cover over the head rest was a three hand job. It was seriously the hardest part of getting these seats back together. I would have swore that they made it too small. But after some serious tugging and stretching, over multiple tries, I finally was able to get them back together.

To get your new covers on and your seats back together, theoretically you can reverse the process shown above...theoretically.
Twenty year old foam cushioning does hold up well. I literally had to glue my bolster padding back together. I then added some floor insulating foam with some spray adhesive to hold it all together and also, to fill them out more. It is surprising how much they had degraded.

Image

After lots of stretching and adjusting and stretching and tightening and more adjusting and stretching, you end up with something like this.

Image

I added universal seat warmers to the butt and back cushions. Fingers are crossed.

Image

Finished seat back.

Image

I painted the plastic trim to match.

Image

On the seat bottoms, I added about an inch of high density foam with spray adhesive.

ImageImage

Work progressed faster with a helper.

Image

First seat finished.

Image

Test fitting both in the car.

I found using both hog rings and zip ties advantageous in reupholstering my seats. I know some debate using one or the other. Both will work, but in some circumstances and spaces it can be easier to use one and vice versa.

Also, I had to compromise the desired end result for time's sake. Even after adding all the extra foam cushioning, I needed more. You may notice the bolsters aren't completely taught near some of the seams. I did not have the time to pull the seats back apart, glue more foam in place, shape it, and put it back together again. So, the finished product doesn't look exactly factory. It somewhat reminds me of a leather recliner, with big puffy arm-wrests. The favorable aspect of this compromise is that the covers should not tear as fast as they would, because not as much tension is applied on the material, which allows it some space to flex and move under pressure.
