Every mom wants to know their baby is sleeping on the safest crib mattress. That's why Nook's products have passed some of the most rigorous testing standards in the world to meet GREENGUARD Gold standards for the lowest chemical emissions. Nook's products are certified to have the lowest measurements of chemical emissions such as VOCs, which means Nook products help promote a healthier indoor air quality and our commitment to the environment.

Global Organic Textile Standard

Internationally recognized as the toughest organic textile standard, this certification requires: that our products contain at least 95% organic fiber; that none of our products are treated with bleach, formaldehyde or any other toxic substances; that we use non-toxic dyes; and that our products are manufactured in facilities that enforce strict social and environmental standards, treating employees and the Earth with respect.


Oeko-Tex textiles and fabrics are certified free of harmful chemicals and are safe for human use.  


Buying products made with CertiPUR-US® Foam means you're foam is: Made without ozone depleters; made without toxic flame retardants; made without mercury, lead or other heavy metals; made without formaldehyde or phthalates and has low VOC emissions for indoor air quality (less than 0.5 parts per million).

Oregon Tilth Certified Organic (OTCO)

The OTCO certification is given to companies by Oregon Tilth, a non-profit organization dedicated to supporting  organic food and farming. Its mission is to educate about the need to develop and use sustainable farming practices that prevent environmental degradation.

Forest Stewardship Council

FSC certification ensures that products come from responsibly managed forests that provide environmental, social and economic benefits. 


The bluesign® system is the solution for a sustainable textile production. It eliminates harmful substances right from the beginning of the manufacturing process and sets and controls standards for an environmentally friendly and safe production. This not only ensures that the final textile product meets very stringent consumer safety requirements worldwide but also provides confidence to the consumer to acquire a sustainable product.
