What you are looking for are called sinuous wire springs. The spring material comes in different gauges and in big long rolls. The springs are cut to whatever length you need. If you tell me how many springs you need, and what length they need to be, I can cut them and "D" end them for you. They need to be "D" ended so they don't slip out of the clips that hold them. I can also send you stake wire and clips to attach the stake wire to connect the springs together so they act as a unit. Here are some pictures of the spring material and the plain cut end and an end that is "D" ended. Also, check out this tutorial on spring repair: Seat Spring Repair
No one lives forever, the trick is creating something that will.
