I got my seat covers from JC as well, and either in the instructions, or somewhere in the archives here it said to put the burlap between the cotton batting, and the seat cover to allow the seat cover to move a little bit when sat on. I didn't see anyplace that said hog ringing the padding down would help. I also put a one inch thick piece of seating foam between the burlap and batting. It made putting the barrel clips on more difficult, but the seat sure feels nice. Also Tim where did you find coir like material? I would like to replace the matting under the fiber board on the interior fire wall.
