Three years ago I found a spotless like new front seat for my 85 300D.
The passenger seat on the other hand is in SAD shape, sitting in it feels like sitting in a chair a 450 pound man sat in for 20 years--its just dead slack.
What's the easiest way to fix this--I have fiddled with seats and doing upholstery is not that much a black art to me, but just the same, I dont want to hand make a chair.
Besides plying junkyards for a replacement, whats the "REPAIR" solution...
