Hi aredman71,
When you are down to final choices that are between “good and good” and there are no clear winners between them then I would use the suggestions in post #2 here to help you decide but it will really come down to a matter of “best judgement” based on all the objective, subjective, and intangible parts of your personal value equation that are most important to you or on which one you find yourself leaning towards based on your conversations.
I would also keep in mind that while both would make great quality/value choices … Select Foam has had some history of delays in communication and customer service lapses for the minority of their customers that have issues that come up after a sale (see my comments here and some examples here and here and here). They have always been resolved to my knowledge but they they tend to take too long or communication is sometimes poor and these types of issues can be a source of significant frustration for the minority of their customers that experience them (and for me as well).
