Hi meraki1990,
Post #3 here earlier in this topic describes some of the differences between the some of the Dreamfoam Ultimate Dreams mattresses (their regular latex model, the Eurotop model, and the Natural model) and their Freedom mattress.
The density of polyfoam is an important factor in its durability but it has little to nothing to do with its firmness. Both low and high density polyfoams are available in a wide range of firmness levels from very soft to very firm.
While there are no weak links in the Freedom mattress in terms of the quality/durability of the materials and like the other Dreamfoam mattresses as well they are also great value in their budget range, this is something that only you can decide based on your budget, the type of mattresses and materials that you tend to prefer, and all the other parts of your personal value equation that are most important to you. There is 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.
