What are the best ways to protect your child from mattress off-gassing?

Mattresses outgas less over time. 



A polyethylene wrap will help and off-gasses less than the mattress itself. 



A cotton/wool mattress cover will not block off-gassing fumes. 



Probably a combination of both would be your best bet. The polyethylene would block more emissions, and the mattress cover on top would give more comfort.
