Toxic chemicals found in children’s mattresses may contribute to cancer and brain development issues, warns a University of Toronto study urging safer bedding options.

TORONTO, Canada — April 16, 2025:
A new study from the University of Toronto has raised significant health concerns after discovering that many children's mattresses emit toxic chemicals, potentially causing cancer, hormonal disruptions, and impairments in brain development.
Published in the peer-reviewed journal Environmental Science & Technology, the study examined the air quality around the sleeping areas of 25 children between the ages of six months and four years. It found elevated levels of volatile organic compounds (VOCs) such as phthalates, flame retardants, and UV stabilizers—substances widely known for their adverse effects on human health.
Researchers noted that the body heat and pressure exerted by children while sleeping accelerated the release of these chemicals from the mattress materials, particularly polyurethane foam and plastic-based components. The proximity of a child's breathing zone to the mattress surface further increases their exposure.
"These chemicals are not just present—they're being actively emitted into the air our children breathe while they sleep," said Jane Houlihan, research director at Healthy Babies, Bright Futures. She highlighted that current safety testing does not adequately consider real-world child use, such as body heat and physical contact.
The mattresses tested, manufactured in North America using components sourced from the U.S. and Mexico, are commonly sold throughout the region. Despite their compliance with existing safety standards, the findings suggest a need for more rigorous regulations.
As a safer alternative, researchers recommend using mattresses made from organic cotton or other natural materials, though they acknowledge that affordability and accessibility may limit widespread adoption.
Experts are now calling for urgent policy reforms to regulate the use of hazardous substances in children’s sleep products, warning that failure to act could lead to long-term public health consequences.
The study reinforces growing calls from pediatric health advocates and environmental groups to prioritize non-toxic, sustainable design in children's products.
