Seat foams are made in the Greater Philadelphia area by the orginal company who supplied GM (Yes we tracked them down and they happen to be local to us!).
 
The proper fit and feel of the seats are of the utmost importance for the iconic A-bodies. The seat foam will set the final height of the seat (for those of you who have exprienced your head touching the headliner) and can even push the driver closer to the steering wheel. They also dictate the overall pull and fit of the seat covers. The molds for these foams were replicated to have the same contour, density, and dimensions as the original seat foams. 
 
Samples of these foams have been put through the ringer to ensure the best fit and feel before the final production was approved. 
 
Seat foams are sold in a set per bucket seat (one upper and one lower).
