Hi meyerba,
There is more about the most important parts of the “value” of a mattress purchase in post #13 here but Dreamfoam is one of the members here which means I think highly of them and I believe they compete well with the best in the industry and all their mattresses including the Freedom mattress would certainly be a good quality/value choice.
It uses synthetic continuous pour Dunlop made by Mountaintop foam which is a good quality material (although it’s also the least costly version of latex). There is more about the different types and blends of latex in post #6 here.
The 12 in 1 customizable is a similar component design (three 3" layers) that can also be rearranged in different configurations but it uses 3 layers of 2 lb polyfoam (which is also a good quality material) instead of synthetic latex but it doesn’t contain any memory foam.
