Hi mattresslook,
I don’t normally have the time to do the more detailed research on websites for each of the members here but I did look at the Select Foam site and they have the 8" Cirrus-EX here and the Dreamfoam site and they have an 8" memory foam mattress here. Several of the others would also have mattresses that are in your height range as well.
The better options and possibilities I’m aware of in the New York City area are listed in post #2 here.
