Hi agupte,
The better options and possibilities I’m aware of in the NY city area are listed in post #2 here and there is a more categorized list with more detailed descriptions of many of them in post #7 here.
Scott Jordon and the Berkeley Ergonomics mattresses are included in the last section of the second list that for most people would have the better quality/value in the area but of course each person can have different ideas about what is most important in a mattress purchase and their own personal value equation so some of the other options may be better choices for some people. I don’t keep a list of the specific mattresses that each retailer or manufacturer has on their floor (which would be an impossible job) but some time on each website and a few phone call will identify others that make or sell mattresses that meet your criteria as well (latex/innerspring hybrids).
