Hi Agent smith,
Hopefully post #7 in this thread will help you out a little bit.
I also agree with your comments about both Fluffo and Southerland.
Fluffo is not “typical” of many local factory direct manufacturers in that they don’t offer latex as a choice and seem to be less materials focused. They do offer memory foam without innersprings though. I suspect that their polyfoam may be higher density than larger manufacturers but I would want to confirm this before I purchased anything from them.
I don’t think that “innersprings” are a real problem though in most of the mattresses sold today because the “weak link” of most of these mattresses is the foam above the innersprings rather than the springs themselves. Many people blame the innersprings for the premature sagging or softening of their mattress when the real culprit is the foam that was used above it. Of course there are some poor quality innersprings as well in the lowest budget ranges but innersprings themselves are not nearly as big an issue as low density foam.
Southerland does make some latex and polyfoam mattresses but the prices (as shown here) I have seen seem to indicate that in some outlets (not all) they are somewhat overpriced and should be heavily discounted to put them in a reasonable “value” range. If they were available at lower prices or if the listed prices I’ve seen in some outlets were lower, they may be worth considering. Some thoughts about them are in post #2 here.
Overall you have some better local choices but it may well worth using your better local options as a testing ground to decide on a “prototype” for an online purchase depending on the prices you encounter compared to similar mattresses available online.
