Hi Just right,
There is some good information on the Strobel site but also some very inaccurate and misleading information as well that is more about fear mongering and selling mattresses than it is about providing accurate information to consumers.
Their information about wool fire barriers as well as viscose/silica inherent fire barriers are examples of some of the “bad” information.
You can read more of my thoughts about their site and the information there about wool (and fire barriers in general) in post #2 here and post #2 here and post #2 here (and the links it contains). Quite frankly I think their wool information is ridiculous and they lose much of their credibility with me when they post information like this.
