Hi RRSNH,
Yes … I do think highly of Ken and Arizona Premium.
Yes … the product is accurately described as 85% synthetic and 15% natural and like all latex would be good quality relative to other types of foams although Ken would be more familiar with it than I am. You can read more all the different types and blends of latex in post #6 here and more about synthetic rubber vs natural rubber in post #2 here. It would be a good choice for those who were looking for “Dunlop latex on a budget” and were OK with the higher synthetic rubber content.
I would imagine it’s because Ken has a good relationship with Latexco and they sometimes offer him products at reduced prices so he can sell them in the DIY section of his site. The reason is mentioned in the description …
