Zinus mattresses are generally considered to be non-toxic.
They are constructed primarily with poly foam / memory foam and those foams are certified CertiPUR-US. CertiPUR-US means their foams are independently tested to be free of the following:
- Ozone depleters (CFCs)
- Toxic flame retardants (PBDEs, TDCP, or TCEP)
- Heavy metals (Mercury, lead, etc.)
- Formaldehyde
- Phthalates
I will add that older Zinus mattresses found themselves in the middle of a lawsuit regarding fiberglass being included in the cover. A lawsuit was originally filed in March 2020, with a related subsequent lawsuit being filed in July 2022.
The allegations of the lawsuit stated that fiberglass used in a fire barrier within the Zinus mattress itself was escaping through the mattress cover (especially when the cover was unzipped or removed), causing potential health hazards.
Furthermore, plaintiffs complained that Zinus did not adequately warn consumers about these potential health risks prior to purchase.
The outcome of this suit ended in a private settlement and was dismissed in August 2023. I will also add that financial terms were never publicly disclosed and the available records do not establish that a court found Zinus liable for these allegations.
All Zinus mattresses produced after 2024 (post-settlement) are fiberglass-free.
Today, Zinus states that its mattresses contain a carbon-rayon sleeve for fiber protection.
