Hi anonymous,
Pure Latex Bliss has higher margins than most smaller manufacturers such as Flexus (although this will depend to some degree on the retailer as well) and they use MAP pricing (minimum advertised pricing) as well which is controlled by the manufacturer so that they don’t lose the business of all the other manufacturers that they also supply to that use Latex International latex in their mattresses. The cost of blended Talalay and 100% natural Dunlop is fairly comparable and while PLB is certainly “better than average” in terms of quality and “value” compared to most mainstream options … they aren’t usually in the same “value range” as many smaller manufacturers. Post #32 here also includes some retailers that sell online and ship across the country that you can call and talk to and make some price comparisons for PLB mattresses.
You are certainly looking at some good options and I’ll be interested in seeing what you end up deciding
