What does CertiPUR-US® certification mean?
Where are Leesa’s Kids mattresses made?
Leesa designs and assembles its mattresses in its Arizona Dream Factory.
What is GREENGUARD Gold certification?
GREENGUARD Gold certified products are low in chemical emissions, maintaining healthy indoor air quality. This certification has the strictest guidelines for total VOC* emissions. It is one of the best certifications in the industry and is important to consider, particularly when purchasing products for kids.
*VOC: Volatile organic compounds, or VOCs, are gases that are emitted into the air from products or processes.
What is GreenFlex Foam?
GreenFlex Foam is Leesa’s biobased mattress foam, made with renewable, plant-based materials and certified as a USDA Certified Biobased Productopens in new window with third-party-verified renewable content.
• 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 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.
How does GreenFlex Foam feel?
GreenFlex Foam has the same responsive, contouring feel as Leesa’s original foam. The open-cell, plant-derived structure makes it slightly more breathable than conventional memory foam, which helps regulate temperature across the night.
Why did Leesa create GreenFlex?
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 BioFoam reflects Leesa’s focus on improving mattress materials without sacrificing sleep performance.
*The 26% biobased content of GreenFlex® BioFoam has been verified through third-party testing under the USDA BioPreferred® Programopens in new window, ensuring compliance with rigorous standards for renewable material content.
