Hi adam s,
The name of the manufacturer on the label doesn’t make much difference because the type and quality of the materials in a mattress and the criteria that are the most important parts of the “value” of a mattress purchase for you (see post #13 here) are much more important than who makes it.
Having said that … Both Brooklyn Bedding and Dreamfoam (they are sister companies … see post #4 here and post #3 here) are invited members of this site which means that I think very highly of them and I believe that they compete well with the best in the industry in terms of their quality, value, service, and transparency.
Yes … as long as they aren’t having a sale that has a bigger discount than the MUG discount (two discounts can’t be stacked together).
