Below are the results from Steve Lozano (he heads up the vibration / acoustical group). Bottom line is that we will be installing 1.0" of the confor foam on the bottom and back cushions where they come into contact with the divan frames. We should have the test cushions ready to ship to Larry on Thursday for a Friday delivery.

Based on the data from the 4 foam samples tested (in numerous permutations of unfinished seat foam configurations), we recommend adding 1" of CF40 (yellow colored foam) to the back of the seat back cushion. We are still working final presentation for program release loads of data that need to boiled down into something easily digestible.
