Hi jdm2008315,
The better options and possibilities I’m aware of in the North New Jersey area are listed in post #7 here.
The Dreamfoam Ultimate Dreams natural latex mattress here may also be worth considering (it uses 2 lb polyfoam in the base layer and natural Dunlop latex as a comfort layer) and most of the latex hybrid mattresses that are sold by Brooklyn Bedding (their sister company) also use a higher density base foam. The tutorial post also includes a link to a list of the members here that sell mattresses online that also make a wide range of latex mattresses.
