Oeko-tex

Oeko-Tex is an international safety standard for textile products that prohibits or restricts the use of substances harmful to the human body in textile products, and is issued only to products that meet the standards.

The Iwata brand receives certification for each product. Not only the main materials (feathers, natural wool, and fabrics), but also all components used in bedding, such as threads and zippers, meet the standards and have been proven to be safe down to the single thread.
