That is a difficult question to answer, because every “chemical” mattress can be constructed differently and treated with any number of synthetic applications. The book, “Sleep Safe in a Toxic World and Toxic Bedrooms: Your Guide to a Safe Night’s Sleep”, list more than 60 different chemicals as being emitted from a memory-foam mattress and 37 chemicals emitting from a typical innerspring pillow-top mattress.

The vast majority of these chemicals are derivatives of petroleum and natural gas.
