Hi daahn08,
The mattress I sleep on is a custom designed version of the Barrington but they no longer sell Talalay latex (only Dunlop).
The mattress factory is one of the members here which means that I believe they are among the best quality/value in the country but of course quality and value has nothing to do with whether a mattress may be suitable for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) or an indication that Dunlop latex is your preference for materials in your mattress. The materials in a mattress are much more important than the label on the mattress so personal testing on a mattress and knowing what is in your mattress are always more important than either the manufacturers name or the model name on the label.
