Hi fujiapple,
I would keep in mind that “safety” certifications and organic certifications are completely different types of certifications that have very different criteria. There is more about the differences between them in post #2 here. There is also more about the different levels of organic certifications in post #2 here and some of the benefits of an organic certification in post #3 here and there is more about the different types of organic and safety certifications in post #2 here.
There is also more about the different types and blends of latex in post #6 here and about certified organic Dunlop latex in post #6 here (there is no certified organic Talalay latex) but all the latex you are likely to encounter (either Dunlop or Talalay that is made with either natural or synthetic rubber or a blend of both) will have a reliable certification such as Oeko-Tex, Eco-Institut, or Greenguard Gold and based on actual testing I would consider any type or blend of latex to be a very “safe” material in terms of harmful substances and VOC’s.
There is more about how Plushbeds compares to SleepEZ in this topic and in post #2 here and a forum search on “Plushbeds SleepEZ” will bring up much more information and feedback about how they compare as well.
Plushbeds uses good quality and durable materials in their mattresses (natural or organic Dunlop and Talalay latex) and they would certainly be a “better than average” choice compared to most of the mainstream mattresses that most people end up buying. They do a lot of internet advertising so they do attract a lot of online attention for those that are looking for a latex mattress. They are also in a higher budget range than many other similar mattresses so I would make some careful “value comparisons” with some of the other component latex options that are available to you.
SleepEz also uses high quality materials in their component mattresses (100% natural Dunlop or Talalay and blended Talalay) and offers many more options in terms of material choices and layering possibilities, has more ways to customize their mattresses, has better exchange options, has a lower cost, has great customer support and service and for most people would be better “value”. They are also a member of this site which means I think very highly of them and I believe that they compete well with the best in the industry in terms of their quality, value, service, and transparency, and of course the 5% discount for the members of the forum is an added bonus.
I believe that their wool is natural (not organic).
