Hi ducksmack,
There is more about the 3 most important parts of the âvalueâ of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesnât turn out as well as you hoped for).
Adding the layers you mentioned would certainly affect the price and I canât speak to whether it would be âbetterâ for you in terms of comfort, firmness, and PPP and whether you would like it more or sleep better on it or not but there would be no lower quality materials or weak links that could compromise the durability or useful life of either one of them.
