The CertiPUR-US certification means that foams are made without ozone depleters, PBDEs, TDCPP or TCEP (“Tris”) flame retardants, mercury, lead, heavy metals, formaldehyde, or phthalates as regulated by the Consumer Product Safety Commission. Materials contain no chlorofluorocarbons (CFCs) and feature low VOC emissions for indoor air quality. The foams are performance-tested, durability-tested, emissions-tested, and content-tested by independent, accredited testing laboratories.
