Need rubber foam for building a pac a seat

[Ben Godard]

I’m making my own pac a seat and I was wondering if anyone knows a good source for getting the right foam and the right thickness as well

These people have the proper density foam for your steel seat.

1 1/2" to 2" for the seat. 2" feels better and won't bottom out. The sidecar can be 1". 1" for the back support. You will need high density foam for a seat or chair. Use automotive covering that will stretch for best results. I have included some pics that might help you with the covering.
