I started out by attaching a layer of vinyl then attached 1.5 inch foam. I am having a hard time hog ringing the cover to the frame having to go through a layer of foam and then through the vinyl to eventually catch a spring. Unfortunately it has been along time since I took the original covers off and I am now wishing I would have documented how it needed to go back together.

The only part I am having issues with is the back part of the seat. Three inches from the back on the cover there is a rod that needs to be hog ringed to the frame. There just doesn't seem to be a good place to attach this rod to.
