Seat spring restoration ?

[Nassau1969]

Is there any solution to tried seats. The covers look great from Legendary interior but the springs have done there job for 40 years now and they are tired and just don't have that firmness anymore they sink right down. Anyone no of a place that does this.

ya know what i did was when i had them apart....i used heavy guage zip ties and tied the rows together.    it really tightened them up.
