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.
