Hi jqwer1,
The better options or possibilities I’m aware of in and around the Monroe Township/Newark, NJ. region (subject to making sure that any specific mattress you are considering meets the quality/value guidelines here) are listed in post #7 here.
If you are in a different area then if you let me know your city or zip code I’d be happy to let you know about any of the better options or possibilities I’m aware of in your area.
As jefmoody mentioned there are also many good online options available as well and the tutorial includes several links to lists of the better online options I’m aware of (in the optional online step).
