I actually had pretty good results rebuilding the seats on my '59 TR3A by cutting out the springs that had rusted through and lacing in fresh springs haravested from an old mattress.  Cleaned the springs with Simple Green, soaked them in Phosphoric Acid, rinsed well, and painted with POR 15.  The rebuilt springs look original, will last forever, compared to the original ones, and ride as firm or soft as you want depending on the stiffness of the springs you add.  Top layered everything with ample felt and high density foam, then installed an upholstery kit from TRF.  The hardest part of the whole thing had nothing to do with the seats themselves, but rather manufacturing the curved strips of wood to replace the ones that had rotted off the frames.
