Hi chip,
Not only are recommendations tricky … they are really impossible except in very generic or “theoretical” terms such as the much more detailed information in the mattresses sections of the site that are part of the suggested reading in the first post I linked including here and here (and the more detailed pages that are in each section) and here. The only specific “recommendations” I would in any way trust online are suggestions from a good manufacturer or retailer after a much more detailed phone conversation about your criteria and local testing experiences who can use their more detailed knowledge of their own mattresses and the “averages” of their customers that seem similar to you to give you some guidance.
The better options I’m aware of in the White Plains / Scarsdale area in either the Connecticut direction or the New York direction are linked in post #3 here. As you can see in post #4 here … there is little in the immediate vicinity that I would seriously consider.
