[ercoupe-tech] Ercoupe Diet

[robertbartunek]

I recently weighed my coupe and it had gained about 45 lbs since it was 
built.  Checking further, I lifted out the seat cushions, opened up the 
upolstery and found them stuffed with some really heavy terry cloth 
type material.  We were guessing that the 2 seats felt like they weigh 
about 40 pounds together so they probably really weigh abot 20-25.  
What is a good, firm material that can be used in the seat cushions 
that doesn't deform a whole lot and is fairly light?
