Hi thebloody9,
The better options or possibilities I’m aware of in the Middletown, NJ area (subject to the quality/value guidelines here) are listed in post #2 here. The only one on the list which I know sells an all latex mattress is Monmouth Mattress in Red Bank which sells OMI (Organicpedic) but these are in higher budget ranges so I would make some very careful value comparisons.
There are more all latex options in the list for the Monroe Township, NJ area in post #7 here but they are a little further away.
