Hi Pura Vida,
Welcome to the Mattress Forum! 
I know it can be challenging finding quality options in more remote locations, especially outside of the contiguous United States.
Regarding finding quality retailers in your area, I have discontinued the provision of listings of potential retailers in various geographic regions (unless they are already approved site members), because of the difficulty in maintaining such lists in a retail landscape that is constantly changing, and most importantly the confusion it was creating with the consumer members who incorrectly assumed that these businesses had indeed gone through the strict vetting and qualification process that is part of becoming an approved member of The Mattress Underground. Such an assumption is unfair to both the consumers seeking assistance, as well as the very businesses and manufacturers who have indeed qualified the be members here of The Mattress Underground.
You can perform a forum search on Seattle or Anchorage or any other area and see what other businesses have been discussed in that region which may be helpful to you.
Whatever business you’re considering, I would always confirm that any retailer or manufacturer that you wish to visit is completely transparent (see this article) and also make sure that any mattress that you are considering meets the quality/value guidelines here.
If you have any questions about specifications or certain products you discover, feel free to post back on the forum and I’ll do my best to be assistive.
In Anchorage, I did a quick search and Mattress Emporium seems to carry Pure Talalay Bliss. Mattress Ranch still lists their Silver and Gold series, which might be options, but you’d need to find out foam densities. Another option is that I see there is a WalMart in your area, and Brooklyn Bedding offers their Best Mattress Ever with the previous latex design on their web site, and while shipping was about $200, it would be more affordable than an all-latex mattress.
Online shopping could be an option for you, but you’d want to check on shipping to your area, availability for returns, etc. You could look online and use the experience and expertise of the members listed in post #21 here who are all very experienced and knowledgeable and specialize in providing the type of help and guidance on the phone that can help you make good choices. There are a wide range of latex and memory foam and other options included in the choices there and I believe that all of them compete well with the best in the industry in terms of their quality, value, service, and transparency, but I’m not sure if you’re interested in that route.
You’ll certainly have quite a few better options in the Seattle area, but you’d have to check into the ability to either transport or ship to Anchorage if you found something you liked.
Off the top of my head, those are some of the ideas I have. If you have more specific questions, I’ll do my best to answer them. Maybe there are site members in the Anchorage area who are more informed and can provide their input.
