I decided to try restore my front seats and thought some might be interested in seeing what is involved.
My drivers seat was starting to pull away in the pleats and was cracked and dirty.
I started by removing the leather from the frame and then started to disassemble the seat. The first thing I found was how the sides of the central pleated part is held down.
Here is a closer look:
The hog rings on the cloth/wire are only attached to the foam at the bottom of the seat. The foam is quite solid, but would break loose quite easily. Here is how it is attached.
The central part is in two pieces that are glued together.
Once separated you can see the top part has pieces of felt that are sewed to the leather and hold down the pleats.
