Hi dogs_007,
The better options or possibilities I’m aware of in the Northern Virginia/DC area (subject to making sure that any mattress you are considering meets the quality/value guidelines I linked in my previous reply) are listed in post #2 here.
Off the top of my head the only retailers in the area that would carry an innerspring/natural fiber mattress would be Urban Mattress and Mattress Traditions (although there may be others I don’t know about).
