TESTED FOR CHEMICAL EXPOSURE & POLLUTANTS
Nearly every eligible City Matttress product is GREENGUARD Gold Certified by UL environment.
That means they’re certified for low chemical emissions.

GREENGUARD CERTIFICATION
The GREENGUARD Certification Program by UL Environment gives assurance that products designed for use in indoor spaces meet strict chemical emissions limits, which contribute to the creation of healthier interiors. Achieving GREENGUARD Certification gives credence to manufacturers’ sustainability claims, backing them with empirical scientific data from an unbiased, third-party organization. All products are tested by UL Environment in dynamic environmental chambers following appropriate test methods. Products are measured for chemical and particle emissions, as they are tested to simulate actual product use. For exposure modeling, measured emission levels are converted by calculation to air concentrations representing what a person will actually breathe. These concentrations are determined based on expected use of the product, amount of product, application process, and the indoor building conditions, including building volume and fresh air exchange rate.
THE GREENGUARD GOLD STANDARD
The GREENGUARD Gold Certification (formerly known as GREENGUARD Children & Schools Certification) offers even stricter certification criteria, considers safety factors to account for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for use in environments such as schools and healthcare facilities. It is referenced by both the Collaborative for High Performance Schools (CHPS) and the Leadership in Energy and Environmental Design (LEED) Building Rating System.
The exposure to individual volatile organic compounds (VOCs), as detected in the C6 - C16 mass spectrometric analysis screen, has been adjusted to allow no greater than 1/100 of the currently published ACGIH® Threshold Limit Values (TLVs) and no greater than one-half of the California's Chronic Reference Exposure Levels (CRELs). In many cases, the 1/100 safety factor reduction of TLVs results in the most stringent requirements for an extensive range of VOCs. A total VOC or TVOC maximum allowable limit takes into account the complex mixture of all VOCs found to be emitting from a product, including those with and without TLVs or CRELs.
