Independent lab testing by NapLab
"I can’t remember the amount of times I’ve gone 'I love this bed!!' while stretching out and rolling around. It’s absolutely fantastic. While providing great support, it’s slightly moldable to the body. We have the king and with my partner moving throughout a the night and early morning, I don’t feel any transfer of movement. Super satisfied!!"

Are Leesa mattresses fiberglass free?
Yes. Every Leesa mattress is made without fiberglass, in a fiberglass-free factory. Instead, they’re crafted with fire-retardant yarn and a rayon barrier. This rayon fiber, derived from 100% regenerated cellulose, creates a protective layer for both safety and comfort.
How long does a memory foam mattress last?
A quality memory foam mattress like the Leesa Original typically lasts 8 to 10 years, depending on how much use it gets and how well it’s cared for. The Leesa Original is backed by a limited lifetime warranty.
Are Leesa mattresses made from safe materials?
Yes. Every Leesa mattress is GREENGUARD Gold certified, made with CertiPUR-US® certified foams, and built without fiberglass in a fiberglass-free factory.
To earn GREENGUARD goldopens in new window certification, Leesa mattresses go through rigorous testing for emissions of more than 360 volatile organic compounds (VOCs). The certification means they meet strict limits on chemical emissions.
The foams are also CertiPUR-US®opens in new window certified, meaning they’re made without ozone depleters, PBDE flame retardants, heavy metals, formaldehyde, and certain phthalates. They also have low VOC emissions for better indoor air quality.
What is GreenFlex Foam?
GreenFlex Foam is Leesa’s exclusive plant-based mattress foam, made with renewable materials and certified as a USDA Certified Biobased Productopens in new window, with 26% biobased content verified under the USDA BioPreferred® Program.
• Plant-based inputs: Natural polyols derived from non-food crops grown on marginal land
• No chemical conversion: The plant oil is a natural polyol, usable as-is—unlike typical bio-foams
• Third-party verified: Renewable content certified under the USDA BioPreferred® Programopens in new window
• Reduced petroleum reliance: Replaces a portion of the petroleum-based inputs used in traditional mattress foam
• Built for performance: Designed to deliver the responsive comfort, pressure relief, and durability expected from a Leesa mattress
How does GreenFlex Foam feel?
GreenFlex Foam has the same responsive, contouring feel as the foam it replaced. Its open-cell, plant-derived* structure makes it slightly more breathable than conventional memory foam, which helps regulate temperature across the night.
How is GreenFlex Foam different from other plant-based foams?
Most bio-foams start with food-crop oils that must be chemically converted into polyols—an energy-intensive process that uses only a fraction of the plant’s oil. GreenFlex Foam uses non-food crops grown on marginal land whose oil is a natural polyol, usable with no chemical conversion—putting roughly three times more of the plant’s oil to use. Its renewable content is independently verified through the USDA BioPreferred® Programopens in new window.
Why did Leesa create GreenFlex Foam?
Leesa developed GreenFlex Foam in-house as part of its ongoing commitment to more thoughtful materials and better sleep innovation.
The goal was to create a biobased mattress foam that combines renewable materials with the breathable comfort, responsive support, and durability Leesa is known for.
GreenFlex Foam reflects Leesa’s focus on improving mattress materials without sacrificing sleep performance.
*The 26% biobased content of GreenFlex Foam has been verified through third-party testing under the USDA BioPreferred® Program, ensuring compliance with rigorous standards for renewable material content.
