Good to know....

...and it only cost me $400 to find out.

I ordered front seat covers and foam. After a good bit of poking around the forum, I chose Legendary. Some nine months after ordering, the parts showed up. I took the seats/covers/foam to a local shop that's been around for a good 30 years. There are always cool cars sitting around; Nomads, Baccarudas, SS 454 Chevelles, GTOs, Model T&As, too.

The gentleman said they used Legendary seat covers all the time...that they are good stuff. The foam? Not so much. He said my almost 50 year old foam would probably be a better choice 'cuz the 'new' stuff was not UP to snuff. The foam doesn't fit to start with, he said, besides being of poor quality.

I figured (wrongly) that a known good quality seat cover source would also have good quality foam. You know, something nicely reinforced for strength like...say...OEM seats.

Nope.

Sure, putting a hand on a pile of foam is not like sitting your arse on it (unless your backside is 6sq.in. or so), but it took very little 'push' to squeeze the seat foam flat as a pancake when it was sitting on the bench.

A big disappointment.
Just askin here, but did you actually inspect the foam yourself? I wonder if it;s possible maybe your interior guy got hold of some foam from a bad batch? It does happen. I haven't seen anybody else say anything about this. ...not that that means a darn thing.
