Thank you for shopping with us fathersjoy. This Latex Sofabed mattress has an FR Sock that protects the product. When the Fire Resistant part of the mattress is not part of the foam, by law, it has to be part of the fabric cover. We can tell you that the foam itself has no FR chemicals in its make up, BUT the fabric we have to use is FR and therefore has chemicals in it. Please note that there is, however, a way round this. You could visit your doctor and get a note from him stating that you are allergic to the chemicals used in FR treatments and requires a mattress made without them. This is the only way we can ship a mattress that does not comply with the current regulations. Have a great day.
