Hi there -- Thanks for your question. No, Greenguard Gold is principally an emissions testing standard. It is performed on finished products as opposed to raw materials. So a Greenguard Gold certification tells you that irrespective of what went into that product, any off-gassing of VOC's (volatile organic compounds) coming out of that product are extremely minimal (if any) such that the product is deemed safe for use in sensitive environments such as schools and healthcare facilities. In practicality, a lack of harmful chemicals can be a key reason for the lack of VOC off-gassing, but that is not what is being certified.

Be aware that manufacturers — and even more disturbingly, most mattress review sites —will often engage in active or tacit greenwashing by implying that a given certification means more than it really does. This is simply part of their objective to sell you that product.

You can read more about what is, and what isn't, part of the Greenguard Gold certification here:

I hope that's helpful.
