What's this on my seat?
#8 is a piece of fabric that goes between the molded seat foam and the sheet metal seat pan. I assume it's there to prevent the metal pan from tearing the foam. I remember seeing it when tearing apart the seats to install seat heaters.
There's no lining between the leather and the foam. It's leather then foam. Again, this happened to my prelude. I took out the seats and saw the foam right underneath the leather. Maybe different in the S, but doubt it.
Problem is the Clazzios are perforated too, so the dust will come thru. What I'm gonna do is remove the leather and cover the foam with some black fabric using spray adhesive. I'll then put the leather back on and then install the Clazzios. Should solve the issue.
Well, I finally solved the problem and it wasn't the seat foam. There is a thin fabric liner sewn to the underside of the leather. Between the leather and this liner is an additional layer of foam. This is where the problem was. This thin foam layer was completely disintegrated. Once I removed the leather from the seat, I used a small pair of scissors to carefully cut open the liner and gain access to the foam. I vacuumed it all up. Section by section. I also did the seat back. Took be several hours to do it all. Check out the pictures.



While I had the seat apart, I took a picture of the driver's seat pan showing the bolster support. Not sure if this had been shown before:

I also took extra precaution to avoid a scratched panel when putting the seat back in the car:
