Hi batman_for_ever,
As you probably know from reading the forum and from the mattress shopping guidelines here, I believe that local factory direct manufacturers and smaller sleep shops that carry local or alternative brands … both of whom tend to have the knowledge, skills, and ability to help you make much better choices in materials and construction … are usually your best source of quality and value.
I’m not sure what city in NJ is closest to you so I can’t give you specifics for your area but post #7 here and post #4 here will likely be helpful.
