Hi SAmone236,
I would be very cautious about using mattress reviews as a way to assess the quality or value of a mattress purchase (see post #13 here) and I believe they can be one of the worst ways to evaluate or choose a mattress. Almost all of them are written by people who have very little knowledge about mattresses, mattress materials, or what combination of materials would be appropriate for different budget ranges or different body types, sleeping positions, and someone else’s personal preferences. In the case of the particular review you are probably referring to it is particularly misleading (and the subject of frequent questions) and you can see my brief comments about the change in the first part of post #4 here, my much more detailed comments in post #14 here, and Dreamfoam’s comments about the change in post #4 here.
For most people in average weight ranges it would make little if any difference (the comfort layers are usually the weak link of a mattress not the support layers) but for those in a higher weight range that may sink into the base layers more deeply I would consider using a higher density base foam (such as some of the mattresses from their sister company Brooklyn Bedding).
Each person can have a very different perception of the same mattress depending on their body type, sleeping style, perceptions, sensitivity to the firmness of different layers (comfort or support layers), and personal preferences, so a more detailed conversation with a knowledgeable and experienced online manufacturer is usually the most effective way to make a firmness choice (see mattress firmness/comfort levels in post #2 here). If you are still uncertain or uncomfortable with a specific choice after that then it may also be worthwhile considering one of their mattresses that has exchangeable layers so that you can change the firmness of your comfort layers after a purchase.
