Best Organic Mattresses (2025): Certified Nontoxic, Natural Sleep

Organic bedding brand Coyuchi recently launched its own organic mattress, combining cotton, wool, and Dunlop latex atop individually wrapped coils. While Coyuchi’s linen sheets are excellent, I was a little nervous to try the company’s first mattress effort. Bedding is not a mattress, after all, and expertise does not always transfer across endeavors. In this case, though, it did. Coyuchi’s organic Natural REM Mattress is wonderfully firm without being too firm and perfect for those of us who lack a sleeping style and tend to sleep every which way—side, back, stomach. I was never uncomfortable.

The design starts with encased coils on a wool pad and then, like a Midwestern dip, layers in smaller coils, latex, and then wool, and tops it off with an organic cotton cover. There’s surprisingly good edge support considering the distance between the coils and the top, and the mattress provides good motion isolation as well. Coyuchi says the Natural REM can be used with or without a box spring. I tested it for a few months on a box spring and then spent a week with it just on the floor and did not notice a difference. At 11 inches deep, there’s room for a topper, though I did not feel the need.

The cotton and wool layers are GOTS-certified organic, while the Dunlop latex carries the GOLS certification. The material is undyed, which is great for anyone bothered by industrial dyes. As with most of these organic options, the Coyuchi is made without chemicals, foam, or glues. Coyuchi’s Natural REM organic mattress is made to order in the United States and comes with a 100-night trial, which means you can get a full refund if it doesn’t work for you. —Scott Gilbertson
