Saggy seat

TwoDogs
Before I pull my seat out, thought I'd check what others have done to fix a saggy driver's seat.
Yes I know I should lose weight.........
 
Mine is the Jap import leather with reupholsterer in Artamon - $$$$$$$$$$$$$$

 
A lot cheaper to get one from a wreckers or someone parting one out, that way you can get the right trim and possibly the right level of fade to match your other seat.
 
Just need to find one that has only had light bums on it!

Now there's thinking, good idea Skylighter...  
 

Thanks Dude, definitely an alternative.
Haven't checked out my seat to see if it is something I can fix....

Thanks all, good suggestions.

If seat covering is in reasonable condition remove seat. Remove steel plate from the four tension springs being bloody careful not to detach springs from seat frame. Cut piece of fairly dense foam rubber about 20mm bigger than steel plate. ( I have used about 15- 20mm thick foam). Turn foam 90 degrees so that the extra length is forward of plate.
Insert foam between plate and existing seat foam tucking the front up above the forward steel seat frame.
Reattach the four tension springs.  No more saggy early model seat.
Not nearly as difficult as it sounds. I accept beer, tyres, spare parts etc.
Not advisable to swap passenger lower squab as they are handed and a fair [link=mailto:b#@*rd]b#@*rd[/link] to remove from frame.
