Are the mattresses flame retardant?

We've designed and manufactured our mattresses without chemical retardants, but do use an industry-standard "fire sock" made of non-toxic materials. The "fire sock" allows our mattresses to withstand grueling flame-resistance testing and still meet all federal, state, and local fire regulations, including the National Flammability Standard. For more information regarding fire regulations, you can visit the Consumer Protection Safety Agency at www.cpsc.gov.
