Have you heard friends and family complain about “off-gassing” when talking about their new mattress? Most of these volatile organic compounds (VOCs) are to blame, and it’s pretty frightening to think about breathing them in through the night. After all, we do spend about ⅓ of our lives asleep and in our beds. Scarier yet is that too much exposure to these volatile organic compounds has been linked to health problems from chest irritation to cancer. Mattresses made with petroleum-based polyurethane, chemical adhesives and chemical fire retardants off-gas. That's why it is important to do your research when buying a new mattress, and choose a brand that you can trust.
