The Best Organic Mattresses, Fully Vetted and Tested

Naturepedic's highly customizable mattress system makes it possible to satisfy sleeping partners with different firmness levels on each side of the bed. The EOS (pronounced EEE-oz) is a multipart zip-together system. There's a cover that you put over separate layers of foam and individually wrapped coils. It's much more like a traditional innerspring mattress than many on this list, if that's what you're after.

The EOS is made with organic cotton, wool, and latex. It's a big and sturdy mattress that comes disassembled in three boxes. The biggest reason to buy, though, is the fact that you can swap out the five different latex layers for free for 100 nights, giving you the chance to fine-tune your firmness. After that you can still swap them but you'll have to buy the new layers—still a nice option if your body or preferences change, or if you get a new partner who has different needs.

Getting these zippered systems to have totally taut and even edges is a chore I have not mastered; you may end up with a funky-looking corner or two unless you invest some time adjusting. —Martin Cizmar

Naturepedic EOS ranges from $2,199 for a twin mattress to $4,299 for a California King.

It's assumed that most mattress shoppers are selecting between soft and firm, or trying to find a middle ground acceptable to partners with different preferences. But what if your tastes change with the seasons or how achy your muscles are after a long, active day? The Zenhaven lets you choose a side.

Saatva's Zenhaven is made of organic latex protected by an organic wool liner and an organic cotton cover. The two sides, labeled Plush and Firm, don't vary as much as dedicated soft and firm mattresses, with the company claiming an 18 percent difference in the two, but it does offer a nice change of pace. Beyond that, the Zenhaven is pricey but extremely well built (and heavy—this is not a mattress-in-a-box). It has great edge support, sleeps neither hot nor cool, and will last you years. —Martin Cizmar

The price ranges from $1,999 for a twin to $4,799 for an Upper-Flex king.

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

The price ranges from $1,400 for a twin to $2,400 for a California king.

My desire for a natural, nontoxic mattress started when I needed new beds for my kids. I care a lot more about what they're sleeping on than what I'm sleeping on. Still, as much as I love the Avocado Green mattress, it's not cheap. For my kids, I bought the more affordable Kiwi Mattress by My Green Mattress. The Kiwi is similar to our top pick Avocado. It's a hybrid model with pocketed springs and natural materials: certified organic cotton, wool, and latex. It's also something of a rarity; organic twin mattresses are somewhat difficult to find.

One nice twist that makes the Kiwi appealing for kids is the two-sided option. It costs a little more upfront, but being able to flip it over extends its life, which is handy if your kids think beds are actually trampolines in disguise. The Kiwi is definitely a firmer style, but I think it's comfortable, and my children loved it when they were younger. —Scott Gilbertson

The price ranges from $775 for a twin to $1,699 for a California king, although the mattresses are often discounted.

Essentia’s Tatami is vegan, meaning there’s no wool or animal byproducts used, and all materials have been sustainably sourced from farms that follow sustainable and ethical farming practices, including fair trade and labor standards. The mattress has a zippered organic cotton cover that can be easily removed for cleaning, and it has a nontoxic, allergy-free Kevlar fabric barrier. The mattress is made of an organic latex support core with holes for breathability, and the active organic foam helps spinal alignment and contouring support for pressure points.

Without springs, the Tatami is super-comfortable, and the foam really conforms to your body’s curves and pressure points. The Tatami has free shipping, a 120-night sleep trial, and a 20-year warranty. The organic, sustainably sourced, and sustainably made bed is expensive, but it delivers on its high price by being well-balanced with both structure and support (without needing springs). —Molly Higgins

The Awara Premier Luxury Hybrid mattress has a comfy (and cool) wool and rayon blend quilted cover top, followed by a layer of sustainable, GOLS- and FSC-certified organic foam, with coils on the bottom for spinal support and structure (including four handles for easier moving). This 12-inch mattress is listed as a 6 on the firmness scale (with 10 being the firmest), and it was slightly more firm than I usually like, but it was still comfortable.

I always slept coolly with that quilted top that helps increase airflow. The edge support was pretty solid, although the top tended to bubble up in certain areas. The cool silkiness just makes it feel elevated—you can tell it's well-made using solid materials. I really liked this luxe organic model, I just wish it were a tad more plush. —Molly Higgins

The price ranges from $799 for a twin to $1,998 for a split king, although the mattresses are often discounted.
