I have one but don't think it is comfortable (gives me neck pain, which gives me a headache), but they sell pillow cases that will block (some? most? a few?) chemicals from coming out of it. I bought a mattress cover like that for my kids' mattresses. Keeps chemicals, mold, etc., from seeping out. I got it on amazon. It's like hypoallergenic but blocks more than just allergens, or so they claim. Or maybe they just parted this fool with her money. But it might be worth a try rather than just stop using it since they are a little bit pricey.
