What are the dangers of a polyurethane foam pillow?

Polyurethane foam pillows can pose several dangers, primarily due to their chemical composition. They may emit volatile organic compounds (VOCs), which can lead to respiratory issues and allergic reactions in sensitive individuals. Additionally, some polyurethane foam products may contain harmful flame retardants, raising concerns about toxicity. Lastly, if the pillow is not adequately ventilated, it can retain heat and moisture, potentially leading to mold growth.
