Hi LatexQuest,
Just for the sake of clarification … 6 Day Mattress is one of the better “possibilities” in the Seattle area but not a specific recommendation. Pure Latex Bliss mattresses have MAP pricing (minimum advertised pricing) and there are some dealers that sell them for this but dealers are allowed to sell for less as long as they don’t advertise it and they are certainly available for less than their suggested retail prices. If you do decide on one of their mattresses there are some PLB dealers that will ship across the country listed in post #32 here that you can call to use as a pricing reference point and if you do decide to make some pricing comparisons I would start by giving Jeff a call at Matt-To-Go who is one of the members of this site.
There are some comments about Astrabeds and some of their sister companies in post #2 here and in post #3 here and a forum search on Astrabeds (you can just click this) will bring up more information about them as well. They have recently introduced a new latex lineup that uses organic Dunlop latex and you can see some comments about them in posts #6 and #7 here).
The choice between Dunlop and Talalay is a preference choice not a “better/worse” choice and you can read more about the differences between them in post #7 here but the most reliable way to know which type of latex you tend to prefer would be based on your own personal testing and experience.
While both Astrabeds and Plushbeds use high quality materials and there are no lower quality materials or weak links in either of them … I would be cautious about only considering the most heavily advertised manufacturers and make sure you make some careful “value” comparisons because there may be some better value options available to you among the list of of online component latex mattress manufacturers that also make similar mattresses that are linked in the tutorial post (in the optional online step).
