Hi passat,
You can see my comments based on my conversations with them in the Seattle list here. There are also many reviews about them online at yelp reviews and google reviews
The Pure Latex Bliss mattresses certainly use good quality materials and don’t have any “weak links” in their construction and materials although there are a wide range of firmness choices so it would be important to make sure that the one you choose is a good match for you in terms of PPP.
Post #32 here also includes some online retailers that ship PLB mattresses across the country that you can use as a “value reference” when you are making a local purchase of one of their mattresses.
