I tossed mine because they are all worn (differently) from 60+ years of someone sitting in them. One of my upholstery friends told me long ago that you would need to replace a number of the springs if you had one broken one because they collapse in a large area around your butt but only one or two will actually break. If you replace one with a new one, it will poke you. I am sure someone out there may want them if rebuilding a seat and wants old ones to save some $$ but, I like thew foam so much better!
