Before...
After....
(*dont know why my phone made the floor look yellow!)
Still need to add about 50 hog rings and pull it tighter but the wife wanted me to do other stuff so I had to stop. BTW, I converted the bottom from 'high spring' to full foam.
I replaced the springs with a ridged lower but it feels perfect when sitting in the seat. It may be a little stiffer than if it had the lower seat springs but it feels perfect to me.
