"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!!"

How long does a memory foam mattress last?
Most memory foam mattresses last for 8-10 years, depending on how much use they get and how well they’re cared for. Memory foam mattresses last longer than traditional innerspring mattresses.
How to unpack a mattress in a box?
We recommend that you move the box into the room where you will be setting up. Then, proceed as follows:
1. Lay your Leesa Mattress on its side, next to the foundation or on the floor. If you use a sharp object to open the box, you risk accidentally slicing your Leesa.
Unboxing on your own? Try putting your foot on one of the box flaps to keep it in place while you pull out the bedroll.
2. Position your rolled up Leesa on any solid or slatted foundation and remove the outer layer of plastic wrap. You'll notice that your Leesa has already started to expand at this point.
3. Unwrap and unfold the mattress and tear away the inner plastic. If you tear the inner plastic at the top of the bed, you can pull it straight down and off like a sock.
4. Keep an eye on your Leesa as it expands and takes shape.
Please keep in mind that your Leesa may take up to an hour to fully expand and a few days to fully firm up. Any odor will dissipate quickly after installation.
Are Leesa mattresses fiberglass free?
Our mattresses contain no fiberglass. They are crafted in our fiberglass-free factory using fire-retardant yarn with a rayon barrier. This chemical-free rayon fiber, derived from 100% regenerated cellulose, creates a protective layer that ensures both safety and comfort.
Are Leesa mattresses made from safe materials?
Yes! Leesa mattresses are designed with your health and safety in mind, adhering to stringent safety standards that ensure a healthier sleep environment. Additionally, we don’t use fiberglass in our mattresses, and our entire factory is fiberglass-free.
Every Leesa mattress is GREENGUARD goldopens in new window certified after undergoing rigorous testing for emissions of more than 360 volatile organic compounds (VOCs). This certification assures that our mattresses are free from harmful chemicals and meet strict emissions safety standards, resulting in minimal VOC emissions.
The foams used in Leesa mattresses are also CertiPUR-US®opens in new window certified, meaning they are made without ozone depleters, PBDE flame retardants, heavy metals, formaldehyde, and certain phthalates. They also have low VOC emissions, ensuring better indoor air quality.
Can I try Leesa in a store?
Yes! You can try and buy Leesa Products at your local West Elm or Pottery Barn store, or nationwide at other select retailers. To find a retail store near you, visit:

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.
