Hi bobfrog,
Both Brooklyn Bedding and Dreamfoam are members of this site which means that I think very highly of both of them and that I believe they compete well with the best in the industry in terms of their quality, value, service, and transparency. A forum search on Brooklyn Bedding or on Dreamfoam (you can just click both links) will bring up hundreds of posts with comments and feedback about both of them (although many of the Brooklyn Bedding posts will be from the time they sold different mattresses than the one they are currently selling).
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful quality/value comparisons between mattresses.
Outside of PPP (Posture and alignment, Pressure relief, and Personal preferences) which is all about how well you will sleep, the most important part of the “value” of a mattress purchase is the quality and durability of the materials in a mattress (which is all about how long you will sleep well) and a mattress is only as good as its construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label. Manufacturers all have access to the same or similar materials so the quality and durability of a material in a mattress that is used by one manufacturer would be the same as another manufacturer using the same material regardless of which manufacturer is using it and the price of a mattress will often have little to do with it’s quality or durability.
There is also more about the different types and blends of latex in post #6 here and there is also more about the quality/durability guidelines that I would suggest following in post #4 here that can help you assess the durability of any mattress you purchase or whether there are any weak links in the design (again regardless of the name of the manufacturer on the label). There is also more detailed information about the many variables that can affect the durability and useful life of a mattress relative to different people or other mattresses you are considering in post #4 here as well.
Assuming that the mattresses you are mentioning aren’t “on the edge” of being too soft for you … in terms of quality and durability none of them use any lower quality materials or have any weak links in their design relative to your body weight and they would all be well worth considering.
When you are down to finalists that are all choices between “good and good” (which you are) and none of them have any weak links or lower quality materials in their design (which they don’t) and if there are no clear winners between them then you are in the fortunate position that either of them would likely be a suitable choice and post #2 here can help you make a final choice based on your local testing or mattresses you have slept well on, your more detailed conversations with each of them, your confidence about the suitability of each one, their prices, the options you have after a purchase to change the firmness or exchange or return the mattress, any additional extras that are part of each purchase, and on “informed best judgement” based on all the other objective, subjective, and intangible parts of your personal value equation that are most important to you.
