Can flame retardants from furniture and mattresses disrupt thyroid function?
The research on flame retardants is still building, but early signals point toward cutting back where it is easy to do so.
What the study actually looked at
The paper behind this page is "Halogenated flame retardants, thyroid function biomarkers, attention-deficit/hyperactivity disorder-related traits and neurodevelopment in children: Recent evidence from a Can...." You can read it in Environ Res (2026).
Short version: the research looked at how flame retardants can affect the body. It did not directly test furniture and mattresses, but flame retardants is one of the things people run into when they use furniture and mattresses, which is why parents ask about it.
What this means for you
If cutting back on flame retardants is on your radar, the simplest move is to swap the products most likely to contain it. That is not about panic. It is about picking the easier option when a safer one exists.
One study alone will not close the case. But if you are pregnant, feeding a toddler, or just want less of this stuff around the house, steering clear of flame retardants where you can is a fair call.
The bottom line
The science backs taking flame retardants seriously. Picking flame retardants-free options where possible is a low-effort way to cut how much of it ends up in your body.
