Do any of the styles avoid the use of fire-retardant chemicals?

State and federal safety standards require all car seats meet stringent flame retardancy standards (also referred to as FMVSS 302). For the Mesa V2, UPPAbaby meets this standard without applying any fire-retardant chemicals to the fabric that is in direct contact with the child. The foam that is underneath the fabric is treated to meet this requirement, however, the composition does not include harmful chemicals. Additionally, the Mesa V2 is GREENGUARD Gold Certified which tests for low chemical emissions, VOC’s.
