Hi iveal,
They would be a much better source of information than I am about the specifics of the materials in any of their mattresses. I would guess that the foam density would be 1.5 lbs but I would always confirm specs with the manufacturer.
Brooklyn Bedding and Dreamfoam are sister companies with common ownership (see post #3 here). They are both members of this site which means that I believe they compete well with the best in the industry and they are both fully transparent about the materials they use in their mattresses. They both use American made materials and components and they are both CertiPur certified* as well.

As brass mentioned … their website only shows some of the mattresses that they have available on their Amazon site (Amazon has the complete selection of their products).
