5. Mattresses With PBDE
Many mattresses still come with high levels of PBDE (polybrominated diphenyl ether), which is a harmful compound that can lead to thyroid problems, brain damage, and reproductive issues.Several states have banned mattresses with PBDE, but not all of them. Check the label on your mattress to see what it's made with, and if you see the telltale initials, then it might be a good idea to invest in a new one.
