The following steps will allow you to minimize health risks when choosing a memory foam mattress: Opt for plant-based memory foam, such as that found in the Amerisleep mattress. Not only do they reduce the use of petrochemicals, they increase the breathability and cooling of the mattress. Look for mattresses with CertiPUR-US and/or Greenguard Gold certifications. These certifications ensure your mattress will have low VOC emmissions.Opt for foams made in the US or Europe, as these foams are held to stricter regulations. Choose a mattress with a natural fire retardant sock, such as wool. If this is not available, look for CertiPUR-US certifications which ensure that the fire sock does not contain BPDEs, TDCPP, or TCEP flame retardants.
