Query: The bolster itself is fine. Stiff and supportive

The bolster itself is fine. Stiff and supportive, as the ones in my yoga studio are. However, it came with such a strong odor that it gave me headaches just to air this item out. It's hard to describe what the odor is exactly; perhaps a chemical used in the dye of the fabric? To treat the dense cotton filling? I can't be sure but after three weeks, it still smells and I can't tolerate it anymore. Disappointed to return as I needed this for my home practice.
