Hey shch,
Thanks for the post.
The Bloom Latex Hybrid, in different firmnesses, is a nice feeling line of mattresses, I was able to lie down on these at the last Las Vegas mattress market. Yes this Talalay is Oeko Tex certified, I do know this is a fact.
I understand your comments on Certipur, all of the decent foam guys have this certification, run by polyfoam companies, etc etc etc. Also noted on “minimizing off-gassing” and noted hybrid preference.
Not sure if you have read all of the certification threads, but there is a good mattress certification posthere.
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 also have a reliable certification such as Oeko-Tex, Eco-Institut, Greenguard Gold or C2C and based on actual testing I would consider any type or blend of latex (regardless of whether it is synthetic, natural, or blended) to be a very “safe” material in terms of harmful substances and VOC’s (offgassing).
IMO, by choosing a hybrid with only 1" of poly below the coils, you have certainly minimized off-gassing, but of course, this is a personal decision and preference for you. But if your room is properly ventilated, airflow, etc, you would have a very low emmision rate with the Bloom.
Have you asked any of the Mattress Expert members if they have the coil unit with no polyfoam base layer? I know most of these units have the stabilizing base foam below them, not all of them of course.
Thanks,
Sensei
