Hi donutista,
Dreamfoam and Brooklyn Bedding are sister companies (see post #3 here).
Most of their staff specialize in either one or the other so if you are looking for information about a mattress that is sold by either one I would suggest talking to each one about their specific mattresses. I would avoid emails with any question that can’t be answered in a single sentence or for any question that might have an “it depends” in the answer … which is almost every question that is connected to mattresses. It can often take a long exchange of emails over a period of days before you may even reach a point of knowing which questions are most important to ask or that you didn’t realize you even needed to ask which can be done with a more detailed conversation on the phone in a matter of minutes.
