Best
This rating is for items that are certified by the Global Organic Textile Standard (GOTS). Every component of the rug down to its fibres, dyes and glues (if any) are GOTS certified.
An example would be the Organic Weave brand of rugs that offers the purest and safest option on the market. This category of rugs typically do come with a higher price point and in our opinion, is well worth it in the long run.
