Seat Springs & Comfort
' Z ' springs ,right ? .
This is kinda tricky , I like a firm seat so I usually rebuild the seat frame before giving it over to my Auto Trimmer for finishing .
In all cases , simply tying the springs to - gether with those little wire ties used by the factory , works very well , as it gussets the load of your weight .
I get extra cross ties from junkers and add them as many as I can wherever the springs are less than 1" apart .
I also take the springs from the center to right side of other seats and use them to replace the sagging or broken driver's side springs .
Mny seats with ' Z " springs have sharp over hangs and you can tie " Pool Noodles " in the overhang to firm them up very nicely .
Some vehicle seats are simply too soft , mostly coil typ springs so getting more coils from identical seats and adding the extra coils in the void spaces , helps firm up seat a lot .
Then I always get heavy duty burlap sheets (Professional Gardeners Supply Shop) and wrap it over the whole top of the seat before adding cotton batting , I don't like foam but black or grey foam is very firm , Auto Upholstery Supply Houses sell crappy black/gray foam , the good stuff comes from Furniture Upholstery Supply Houses , co$t$ a tiny bit more some times but the comfort is tops .
The burlap over the whole spring spreads the load out and increases support & comfort greatly .
Lotsa extra labor here as those cross ties and the clips used to anchor the springs are stiff bastards and sharp too ~ you may get lacerated fingers , beware .
Do not trust the Trimmer to do this basic hard and painful works , you must do it your self .
Take some pictures as you go because once you've improved the seat and folks sit on it , they're going to ask how did you do this ? .
