All your questions answered
How big is a California King size mattress?
Leesa mattresses follow the standard size for California King mattresses - 72 inches wide by 84 inches long.
What does the warranty cover?
Leesa offers a limited lifetime mattress warranty that covers the following:
- Deterioration of the mattress resulting in a visible indentation greater than one and a half (1.5) inches that is not associated with an indentation or sag as a result of an improper or unsupportive foundation or base.
- Any physical flaw in the craftsmanship of the mattress that causes permanent damage to the memory foam despite proper set-up and normal use.
- Any physical flaw in the craftsmanship of the cover, including seams and zipper assembly.
Please see our warranty page for full details, terms & conditions.
How does the 120-night sleep trial work?
Every Leesa mattress comes with a 120-night trial. After 30 days of sleeping on your new mattress, if you're not happy with your purchase, the friendly folks on our Comfort Crew can help walk you through the process of returning and refunding.
Whenever possible, we donate any returned mattresses to a 501(c)(3) organization or one of our charity partners. One of Leesa's missions is to be a positive force in the world, so if we can donate a mattress in good condition rather than disposing of it in a landfill, that's the route we're going to take.
For more details, check out our full trial period and return policy.
Are Leesa California King size 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 gold 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® 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.

We make the bed, you make the difference
Since 2015, we have committed to making a positive impact on our communities. We stand firm in the belief that everyone deserves the dignity of a safe and comfortable place to rest. It's a fundamental right, not a luxury. That's why we’ve donated over 43,000 mattresses to those in need, providing more than just beds—offering a foundation for a better future.
Two billion people in coastal regions don’t have access to proper waste management. Our partnership with CleanHub and local communities in India ensures the safe collection and recovery of ocean-bound plastic—and creates sustainable jobs.
