Hi Cooperman,
Dreamfoam and Brooklyn Bedding as well as Arizona Mattress are both members of the site which means that I believe they are among the best quality and value available.
I’m not sure which mattresses you are looking at but you can read a little more about the differences between a latex/polyfoam hybrid and an all latex mattress in post #2 here if that is part of the comparisons you are making.
As you can read in post #2 here … final choices can be difficult but once you have eliminated the worst choices (and both of the manufacturers you mentioned would be great choices) then it’s really up to the parts of your personal value equation that are most important to you.
Forum searches on both will also bring up lots more information and feedback from other forum members.
