Car Seat Foam

[Rod]

Hi All,

I am about to put my repaired front seat covers back on. I am thinking at this point it would be best to replace the foam.

Would anyone have suggestions on what thickness foam I should use (I am thinking 2" / 50mm) but what grading of High Density Foam I should use. I am thinking this foam from Clarke Rubber (https://www.clarkrubber.com.au/products/25083p-high-density-packaging-and-seating-foam-29-200) but I don't really know what the number really mean - 29-200.

Cheers Rod
