Request for clarification regarding 'good' PU foam

I have seen it said a few times on this site that there is good PU foam that does not break down.

I have also seen it said that most PU foam in mattresses these days is bad and does break down, and that is the reason for the massive number of consumer complaints about sagging problems.

So I made this thread to clarify these points so that my knowledge is correct. 

I'd appreciate if the knowledgable posters could answer these questions:

1. How is good PU foam defined?

2. Is there a tangible way to discern good from bad PU foam in a mattress, prior to buying said mattress?

3. Do any manufacturers still use good PU foam today, or is 100% of the PU foam made today crap?  If 100% is not crap, which manufacturers still use good PU foam?

most mattresses in the 70's probably had a small amount of PU foam but such typically a small enough amount that it didn't lead to large body indentations

Good question confused.  I don't have the answer :) but I'll be following the thread.

I think the older mattresses used stuff like cotton batting, dacron stuffing and things like that in addition to some foam. And since they were flippable, if one flipped them regularly as recommended, they lasted much longer. I'm betting they used a higher quality foam as well. But I'm just guessing on that.
