Certified 25% biobased foams have been analyzed to determine percentage of biobased content by an independent, accredited biobased testing laboratory.

CertiPUR-US certified 25% biobased foams meet all of the criteria for our certified foams and in addition have been analyzed by the independent ISO 17025-accredited laboratory Beta Analytic, that specializes in biobased testing services. The percentage of biobased content in the foam is based on the internationally recognized ASTM D6866-22 Method B standard which uses an Accelerator Mass Spectrometer (AMS) instrument to measure how much of the carbon within a product is derived from biomass. The result indicates the percentage of the product’s biobased carbon versus fossil-derived carbon. Certified 25% biobased foams must have a minimum of 25% biobased content. Some of the biobased foams currently certified actually contain higher percentages of biocontent and we anticipate certifying higher percentage levels in the future.

In developing and certifying biobased foams, foam producers are supporting the efforts of upholstered furniture and mattress manufacturers to use environmentally responsible materials in constructing home furnishings for consumer use. Within any one mattress or sofa, for instance, manufacturers may use a combination of CertiPUR-US certified foam and CertiPUR-US certified 25% biobased foam in order to create the optimum balance between comfort, support and durability. When the foam is CertiPUR-US certified, consumers can rest assured that the foam meets our rigorous standards for content, emissions and durability.
