Hi Kjantj35
You have been fortunate to have mattresses last that long with your body type. It would be reasonable to expect that the Ultimate Dreams would have a similar or even better lifespan than most mattresses but it would also depend on the mattresses you were comparing it with. It has better quality materials than many other mattresses at significantly higher prices. How long a mattress will last for any specific person though is really relative to the person themselves as well as the design of the mattress and depends a great deal on how long long it takes for the inevitable foam softening of any mattress to result in the loss of comfort and/or support to a degree that puts you over the line of your specific pressure relief and support needs. You can read more about the relative durability of mattresses and the different factors involved in durability in post #2 here. If you choose a mattress that is just âon the edgeâ of being too soft and providing the support/alignment you need ⌠then foam softening can take you over the line more quickly even though the materials arenât âworn outâ and the same mattress would still be fine for someone else that was still inside the range of their comfort and support needs. I generally wouldnât recommend 4 lb memory foam for someone of your height and weight no matter who the manufacturer was.
There are actually more differences between them than just an extra inch of slow recovery latex.
The Prodigy has the following layers âŚ
2" KoolComfort Memory Foam: 5 lb density. Good quality/density
1" Comfort Foam: 1.3 lb density. Low quality
1" Cool Reaction Slow Recovery Latex: Good quality
2 3/4" CoolAction Gel Memory Foam: 4.1 lb density. Medium quality/density.
6" ComfortLast Support Core: Lower density/quality polyfoam (probably 1.5 lbs)
The Ultimate Dreams has the following layers
3" of 4 lb gel memory foam
2" of 5 lb memory foam
8" of premium base foam (I believe this is 1.5 lb polyfoam).
So Iâm not sure exactly what aspects you are wondering about in terms of the differences between them but if you mean the difference in how they may feel then the âfeelâ of the Ultimate Dreams is similar to the Cloud Luxe but just a little firmer so the difference between it and the Prodigy would be similar to the difference between the Cloud Luxe and the Produgy and you could test this to see what the differences feel like for you (different people may perceive this differently)
The comfort layers of the prodigy are thicker (6.75") than the Ultimate Dreams (5") and with this much thick/soft foam on top (about 2" more) it would be a more risky construction for you because of the possibility of your hips/pelvis sinking down too far before they reached and were âstopperâ by the support layers. This could easily lead to alignment and back issues.
In addition to this ⌠the support layer of the Ultimate Dreams is higher quality than the Prodigy.
Again though ⌠I would be very cautious using 4 lb memory foam at your weight and if I was to purchase any mattress that used it because of its comfort then I would have lower expectations concerning durability.
