Hi billynath1988,
As you probably know Dreamfoam is one of the members of this site which means that I think very highly of them and I believe they compete well with the best in the industry in terms of their quality, value, service, and transparency.
I would also keep in mind though that you aren’t buying the brand and would only be buying one of many mattresses that they make so outside of how suitable any mattress is for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) the most important part of the “value” of a mattress purchase is the type, quality, and durability of the materials inside it and how it compares to the other mattresses you are considering based on all the parts of your personal value equation that are important to you regardless of the name of the manufacturer on the label.
In very general terms latex is more breathable than memory foam so it would tend to sleep cooler than memory foam as well. There is also more about the many variables that can affect sleeping temperature in post #2 here that can help you choose the combination of materials and components and the types of mattresses that will have the best chance of keeping you in a temperature range that you are comfortable with.
There is more about the differences between memory foam and latex in post #2 here but the choice of materials in a mattress would be a preference choice not a “better/worse” choice. Not everyone likes the “feel” of latex (just like many people don’t like memory foam or other materials or types of mattresses as well) so it’s usually a good idea to do some local testing to make sure you like the general feel and performance of latex or any other material you are considering. Both memory foam and latex mattresses come in a wide range of firmness levels but they are very different from each other in terms of how they feel and respond and they each have a unique type of softness/firmness that different people may translate differently based on their subjective perceptions of softness/firmness.
When you can’t test a mattress in person then the most reliable source of guidance is always a more detailed conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart (such as Dreamfoam) and who can help “talk you through” the specifics of their mattresses and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked that they are familiar with, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
The density of memory foam (and polyfoam) isn’t directly related to firmness and any density of memory foam can be chemically formulated to have a range of firmness levels and many other properties as well (see post #9 here and post #8 here). Every layer and component of a mattress will also affect the feel and performance and firmness level of every other layer and the mattress “as a whole” and there are also many variables that can affect the firmness of a mattress besides the firmness of one of the layers inside it (see post #4 here). Density is the most important factor in the durability of memory foam or polyfoam but it has much less to do with how it “feels” and you can’t feel the quality or durability of a material when you sleep on it.
Based on feedback on the forum and on information from Dreamfoam as well … their 13" gel memory foam mattress is closely comparable to the Tempurpedic Cloud Luxe (perhaps just a bit firmer) so you can get a good sense of it’s firmness by testing a Cloud Luxe locally. The Cloud Luxe is Tempurpedic’s softest mattress.
The Dreamfoam Supreme gel memory foam mattress would be comparable to the Tempurpedic Cloud Supreme which would be firmer than the Cloud Luxe (mainly because it has less memory foam in the top layers).
