How to Support Your Latex Mattress

For proper ventilation and support, your natural latex mattress must be used on a slatted wood surface with 1.5 to 3 inches between the slats. To eliminate the need for a foundation, the mattress may be placed directly on a natural wood platform bed–which comes with slats–like those from Dapwood. For the budget-minded, we also offer a roll of wood slats that might work on your existing bed frame, depending on how it’s constructed. Feel free to contact us if you have questions about how to support your new mattress.

Lead Time and Shipping

Mattresses are made-to-order in about a week at the factory in San Francisco, CA; then rolled-up and sent directly to you. They are shipped via FedEx, with the exception of some King and CA King mattresses which are shipped by freight carrier. We offer FREE SHIPPING in the continental USA; to ship elsewhere please contact us for a shipping quote. If you are asked to sign for the delivery, you will need to inspect the package for damage and have the truck driver note any problems, then report the damage to us immediately.

Because these mattresses are hand-made, finished dimensions may vary up to an inch.


Your all-natural latex mattress will be warrantied by the manufacturer to be free from defects in material and workmanship for a period of seven years, though life expectancy should be longer than that when properly maintained. The mattress is designed to conform to your individual shape, which may result in body contouring. This is normal and not a structural defect, but contouring over 1.5 inches in depth below the normal surface of the product is covered by the manufacturer’s Limited Warranty. Compression of 10-15% is normal for plant and animal fibers, and usually takes place in the first 60 days of daily use. To reduce body impressions and achieve the maximum useful life from your mattress, rotate and flip it every 2-3 weeks for the first six months, then continue to rotate and flip it every 3-4 months. Also, sleeping on all parts, including the center, will help avoid bumps where no one sleeps. The natural materials used in these mattresses may have a slight odor upon arrival, which will fade away over time; and we do not warrant for smells. If you are very sensitive to smells, you can contact us to order sample materials prior to purchase. Read more warranty details.

Eco-Conscious Ways to Dispose of Your Old Mattress

Consider offering your old mattress for free on Craig’s List or Facebook Marketplace. Usually there’s someone out there who really needs a mattress, and they will come and pick it up! Or look for a local recycler at  Bye Bye Mattress or Earth911. Please do not send it to the landfill, if at all possible.

Note: Certain states have instituted a mattress recycling program, and we pay a recycling fee when we ship a mattress or foundation into these states. The current fee for California is $11 per item; Connecticut’s fee is $9 each; and Rhode Island’s fee is $10. For more information, see Bye Bye Mattress.
