No help here Tim, my seat was in excellent shape, very firm all
the way across. I even used the original horsehair (rubberized
coir) pad simply replacing the old cotton padding and cover.

If you have broken or weak springs my only suggestion, and the
way I would cope with it, would be to find a donor seat and
scavenge one/ones from that.
