The proposition 65 warnings apply to carcinogenic materials used on furniture surfaces which can be released into the air or accumulate in dust. None of these substances are a conditio sine qua non, there are alternatives. https://www.p65warnings.ca.gov/fact-sheets/furniture-product...

The same warnings and labels are used in the EU, for example for formaldehyde which will be severely limited in its use starting in August 2026. https://easecert.com/blogs/insights/formaldehyde-emission-li...

It may look weird, but personally I prefer a warning to being submitted to toxic substance without my knowledge.
