Hi sideSleeper333,
The “should” part is up to you of course and all I can do is provide information that can help you make a decision about what is best for you but a mattress is only as good as the quality of the construction and materials inside it and its suitability for your needs and preferences in terms of PPP. “Subjective showroom comfort” alone is one of the worst ways to buy a mattress (see this study which indicates that this type of mattress purchase has lower odds of choosing the best mattress than random chance alone). I personally wouldn’t consider a mattress made by a manufacturer that doesn’t provide meaningful information about all the materials that were in it and where you knew that the materials were lower quality than other mattresses in similar price ranges. You can read more about how to know which is the “best” mattress for you in post #2 here and post #5 here.
The best place to start is always post #1 here which has all the information, steps, and guidelines you will need to make the best possible decision. Any material has good and worse versions so no matter which materials you prefer (and your testing will tell you which materials you prefer) it’s important to make sure that it is the best possible quality and durability. I’m not sure where you are located but based on your West Chester comment post #6 here has links to the various lists on the forum that would include the better options that are close to you. As you can see in the “read first” post I linked … an hour or two spent reading the more informative posts and information on the site is always the first step and will put you in a great position (and you will know more meaningful information than a majority of the salespeople at the mass market retailers that sell mattresses) to end up with your “best” mattress.
