Hi RoxCo,
Keep in mind that there are two parts to “support”. The first is the deep support that comes from the deeper layers of the mattress which “stops” the heavier parts of the body from sinking in too far and tilting the pelvis causing misalignment. The second part of support is from the upper layers which “allows” the wider lighter parts (such as the shoulders for side sleepers) to sink in enough and to fill in the gaps in the sleeping profile to help support the curves of the spine. These two types of support together lead to spinal alignment in all of your sleeping positions.
“Value” includes both objective and subjective parts and is really up to each person to determine based on all the factors that are important to them and their own personal “value equation” (many of these in post #46 here.
Based on material cost alone … the Dreamfoam is probably better “value” but both of these are among the best value in the country and the ability to test a mattress locally … especially if you have more specific needs … and all the other factors involved in the link I included are also a significant part of the “value” of a mattress purchase and your own “value equation” is more important than the simple “commodity value” of a mattress IMO.
The DreamBed Beluxe uses very high quality materials and would be a good value and durable choice IMO … but again it’s important to make sure that it “fits” your needs and preferences. The choice between them would be “good vs good” rather than “good vs bad” which is exactly the place where the best final decisions can be made :).
