Hidden hazards: toxic chemicals found in children’s mattresses raise alarm

New research links common sleep materials to serious health risks, with implications for product liability and consumer safety

A University of Toronto study has raised concerns about the levels of potentially toxic chemicals being released into the sleeping environments of children via their mattresses. The research tested 16 of the most common children mattress brands used in North America. Mattresses were tested for 45 different chemicals, some linked to health issues including asthma, or adverse effect on cognitive ability or working memory. 21 of these chemicals were detected in each of the mattresses tested.

Accompanying research tested air levels in the bedrooms of children under four years old and found the highest levels of toxic substances, including phthalates, flame retardants and UV filters, were in the vicinity of the children’s beds. Given the duration of time that children typically spend in and around this area, 18 hours daily average, there are concerns with potential contamination of surrounding air and other objects including toys and clothing that could easily be ingested and absorbed. Compounds found in the chemicals have been linked to health issues including neurological damage, reproductive harm and cancers.

No correlation was found between high toxicity levels and either the country of manufacture of the mattress components or the cost points of each of the brands tested.

Co-author of one study and environmental chemist at the University of Toronto Miriam Diamond stated researchers were ‘very surprised’ by their discoveries. Some recommendations to limit the effects include allowing a new mattress to air outside after purchase. However, the effectiveness of this is dubitable as certain chemicals identified may take years to leave the mattress surface from open air exposure alone. Ultimately the onus is on the manufactures of the mattresses to address the issues with the materials used.
