No, Lull mattresses are generally not considered to be toxic. Their mattresses are confirmed to use CertiPUR-US foams, which is the most common certification to look for on the topic of toxicity.
Mattresses that meet these certification criteria are made without:
- Ozone depleters
- PBDE flame retardants
- Mercury
- Lead
- Heavy metals
- Formaldehyde
While CertiPUR-US is the standard, more rigorous certifications like GREENGUARD Gold provide extra peace of mind for those with higher sensitivities to chemical emissions. Lull mattresses available from their website do not have this certification.
However, the Lull Original, specifically available from Pottery Barn Kids, is GREENGUARD Gold certified.
