Hi jasonsmith,
The new foam is actually about the same price as their previous foam and is certainly not “cheap foam”. It’s a lower density but has higher performance.
You can read some comments about it in the first part of post #4 here, some comments from Dreamfoam in post #4 here, and much more detailed comments in response to one of the members here who changed their “review” in post #14 here but as Everready mentioned this change was in connection to one of their lower priced mattresses that used polyfoam in the base layers.
Their pocket coil / latex mattresses use a pocket coil in their support layers (not polyfoam) and they would be able to tell you any of the other specs you wanted to know about any of the other layers.
Post #13 here also has some comments about reviews in general which can be quite misleading if they are written by customers that aren’t familiar with all the many variables involved with foam specs or aren’t knowledgeable about the “quality” of the materials in a mattress they purchased.
