Nectar mattresses carry CertiPUR-US certification, which means their foams meet baseline safety standards for chemical content and emissions. But “non-toxic” is a marketing term with no legal definition, and the full picture is more complicated. Nectar has faced a class action lawsuit over fiberglass in its fire barrier, a federal recall for flammability failures, and criticism for limited transparency about its materials.
What CertiPUR-US Certification Covers
CertiPUR-US is a foam industry program that tests for a specific list of chemicals. Certified foams are made without formaldehyde, ozone-depleting chemicals, mercury, lead, other heavy metals, and phthalates regulated by the Consumer Product Safety Commission. The program also screens for flame retardants classified as carcinogens, mutagens, or reproductive toxins. Volatile organic compound (VOC) emissions must stay below 0.5 parts per million.
This certification is meaningful but limited. It only applies to the foam layers, not the cover fabric, adhesives, fire barrier, or other components. And CertiPUR-US is an industry-run program, not a government standard. Nectar does not hold GREENGUARD Gold certification, which is a stricter, independent standard that tests the finished product as a whole for chemical emissions, including materials beyond just the foam.
The Fiberglass Fire Barrier Issue
The biggest safety concern with Nectar mattresses has been fiberglass. A class action lawsuit alleged that several Nectar models, including the Classic, Premier, Luxe, and Ultra, contained a flame-retardant sleeve made of fiberglass that could leak tiny glass fibers into the surrounding environment during normal use. Outer mattress tags listed “Glass Fiber…23%” as a material, but the lawsuit claimed this wasn’t an adequate warning about the health risks.
Exposure to airborne fiberglass can cause intense skin and eye itchiness, breathing difficulties, throat irritation, and stomach irritation. Once airborne, glass fibers can enter HVAC systems and spread throughout a home. The lawsuit also alleged that Nectar denied using fiberglass in 2019, only acknowledging it after consumer complaints. By 2022 or 2023, the company added a tag warning that removing the cover created a “risk of injury or death,” but still did not clearly disclose the fiberglass content.
Nectar now states that its modern mattresses use rayon, or a rayon and polyester blend, as a flame barrier instead of fiberglass. If you purchased a Nectar mattress before this change, your mattress may still contain a fiberglass inner sleeve. The simplest way to check is to look at the law tag sewn into your mattress for any mention of glass fiber in the material composition.
What’s Actually Inside a Nectar Mattress
Nectar mattresses are made primarily of memory foam layers, including gel-infused comfort foam and a support base. The cover uses cooling fibers designed to wick moisture, and some models like the Nectar Ultra include phase-change materials for temperature regulation. Nectar considers its specific foam formulations proprietary and does not publicly disclose foam densities or detailed chemical compositions.
That lack of transparency is worth noting. You can confirm the foams are CertiPUR-US certified, but you cannot independently verify the full list of chemicals in the adhesives, cover treatments, or other non-foam components. For a mattress marketed as safe and non-toxic, this is a gap.
Off-Gassing After Unboxing
Like all memory foam mattresses shipped compressed in a box, Nectar mattresses produce a chemical odor when first unwrapped. This smell comes from volatile organic compounds released as the foam expands and reaches room temperature. The odor typically fades within a few days.
To minimize exposure, let your mattress air out in a well-ventilated room before sleeping on it. Opening a window or running a fan speeds up the process. While CertiPUR-US limits VOC emissions to low levels, the initial off-gassing period can still be noticeable, especially for people sensitive to chemical smells.
The 2022 Federal Recall
In a separate issue from the fiberglass lawsuit, the Consumer Product Safety Commission recalled specific Nectar Premier mattresses for failing to meet federal flammability standards. The recall covered king-sized models made on September 24, 2021, and queen-sized models made on September 27, 2021. This was a limited production-date recall, not a blanket safety issue across the entire product line, but it does reflect a lapse in quality control.
How Nectar Compares to Stricter Standards
CertiPUR-US is the most common foam certification in the mattress industry, and having it puts Nectar on par with most other bed-in-a-box brands. It is not, however, the highest standard available. Mattresses with GREENGUARD Gold certification undergo testing of the entire finished product for over 10,000 chemicals and meet emission limits strict enough for use in schools and healthcare facilities. Organic mattresses certified by GOTS (Global Organic Textile Standard) or GOLS (Global Organic Latex Standard) go further still, requiring organic raw materials throughout.
If your priority is minimizing chemical exposure, particularly for children, people with chemical sensitivities, or anyone with respiratory conditions, a mattress with GREENGUARD Gold or organic certifications offers more verified assurance than CertiPUR-US alone. Nectar’s foams pass a reasonable safety threshold, but the brand’s history with fiberglass, its limited material disclosures, and the absence of third-party whole-product testing leave gaps that stricter competitors have filled.
