Mattress Forum

I have it configured with soft over medium over firm cores.  I was advised that this is the best configuration because it gives me the most options if I want to adjust firmness. But I presume those options are for making it more firm, not less firm. 

Do you think I should consider exchanging the 2 firm pieces and 2 medium pieces for soft? Would that be way too soft?

Would soft over soft over soft be bad for my back?  If so, I wouldn't wanna get that for that reason alone.
