These days there is more to consider when buying a mattress than the perfect size, price and firmness. It is also important to consider the origin of the mattress materials and figure out if the materials in it are a threat for their health, the environment, or both.
Certifications can be a key element when it comes to finding out if a mattress proceeds from a green company or uses green materials. A reliable green mattress certification is Certi-PUR-US, another good way to find out about the origin of the materials in the mattress, is by looking for full disclosures on the precedence of the materials. Buying a mattress is a very important decision, it affects your health, mood, and productivity that is why knowing about certifications and materials can be of great help when making such an important decision.
Most conventional mattresses are made of petroleum-based polyester, nylon and polyurethane (PU) foam (all of which emit VOCs, especially when new) and treated with flame-retardant (FR) chemicals, such as boric acid, silicone and phosphates. They can also be wrapped in barrier cloths made from flame-resistant fibers, such as melamine and polyvinylidene chloride.
These chemicals are toxic to your body which can act like an irritant on your skin. Toxic chemicals can also effect your internal health and cause problems with hormones and many other systems in your body.
So just do a little research and try to find materials that are made with organic cotton, untreated wool, or natural latex. At a minimum, you want your top comfort layer on your mattres to be made with green materials.
