Hi vwinslow,
I think if anything this video could add to the confusion. The Flobeds video has been brought up on a number of occasions on the forum and I have commented on it in posts such as post #4 here and in post #4 here. It certainly doesn’t reflect the reality that many people have slept on a Dunlop latex mattress for decades (you can see an example here of one that is almost 50 years old).
I would completely avoid the temptation to call one type of latex better or worse than the other and just treat them as being different with each one having different properties that some people would prefer over the other. I would treat the choice between them as strictly a matter of preference and not as a “better/worse” choice at all which IMO completely misses the point.
There is more about the different types and blends of latex in post #2 here and in post #6 here and more about the “feel” or Dunlop vs Talalay in post #7 here.
