Hi newkidontheblock,
That’s because they aren’t members here (although I have talked with them and they are on the local list of “better” options).
You are certainly in a good position and choosing between “good and good”. Post #2 here may help you make final choices but I would keep in mind that every difference between a mattress you have tested locally and one you order online (including the type of latex, the firmness of each layer, the thickness of each layer, the cover, and the type of quilting) will affect the feel and performance of the mattress. Any differences may be better or worse for the needs and preferences for any specific person and of course the different options to choose materials or exchange or re-arrange layers may also be an important part of your personal value equation.
