Hi Annie,
Yes … the Original Mattress Factory is a regional factory direct outlet and is the type of outlet that I was talking about and often recommend. In your case they are the only factory direct outlet within 100 miles of you so I would certainly make them a big priority in your mattress search. They are one of the larger regional factory direct manufacturers and have very good value.
There is more information about the Raleigh area in this thread.
