Best Organic Mattresses (2026): Certified Nontoxic, Natural Sleep

Conventional mattresses often have questionable materials in them. Everything from polyurethane foams with formaldehyde and TCEP (a flame retardant) to phthalates can end up in nonorganic mattresses, off-gassing into your home. How much these substances affect you isn’t scientifically settled, but it’s not hard to avoid them altogether with a mattress made from natural, organic materials. Most organic mattresses are made of a combination of wool, natural latex, and cotton. The construction is similar to conventional mattresses but without the chemicals.

I’ve been testing and sleeping on organic mattresses for seven years now, and these are my favorites out of the dozens I’ve tested. All of the prices below are for queen-size models unless specified.

Updated August 2026: We've revamped this guide to narrow down our picks and added some organic toppers and sheets you can grab to round out your organic bed.

After years of testing, the Avocado Green hybrid mattress remains my favorite organic mattress. It’s the only mattress my wife and I can agree on. She likes a soft mattress, and I prefer something firmer, and the Avocado somehow manages to be both without being too much of either. It’s also good for combination sleepers like me, who spend time in just about every position in the course of a night. After nearly five years of sleeping on this Avocado, it’s proven its durability—there’s zero sagging or other issues.

Avocado also has the most organic and nontoxic certifications out of all the mattresses I’ve tried. The company’s organic, nontoxic mattresses are made in the USA from GOLS-certified organic latex, GOTS-certified organic wool, and GOTS-certified organic cotton. The company also does extensive PFAS testing to ensure there are no forever chemicals in your mattress and carries a Made Safe certification as well.

While the sustainable, organic materials and eco-friendly construction were definitely part of the initial appeal, what really stands out about Avocado in all my testing is the comfort. The Avocado Green mattress uses pocketed coils, which are steel coils wrapped in a sleeve (the pocket) made of fabric. Each coil moves independently, which increases motion isolation. That means you get the support of an innerspring mattress while minimizing “motion transfer,” meaning you don’t feel like you’re on a trampoline every time your partner rolls over. The Avocado Green is 11 inches thick and arrives compressed. Once expanded it’s heavy and somewhat unwieldy, so make sure you move it around before you uncompress it.

Avocado offers a one-year trial, a 25-year warranty, and free shipping on all Avocado mattresses. Notably, the 25-year warranty covers any defects or issues, including visible indentation “equal or greater than one and a half inches.” If you prefer a plusher feel, there’s also a pillow-top option for this mattress, just select the plush version when buying.

Avocado Green ranges from $1,499 for a twin to $2,899 for a California king.

Birch’s Luxe organic mattress is another well-rounded option that offers good support but also a good bit of plushness and pressure relief (Birch calls it a medium-firm mattress). It’s a little on the bouncy side, meaning that it springs back a good bit when you roll around, which makes it a good choice for back sleepers, since you’re well supported.

The Birch Luxe is made of natural materials and uses individually wrapped steel coils, which are topped with layers of organic latex and wool, capped off with a GOTS-certified organic cotton cover. The finished mattress does not have a Made Safe certification, but it does carry Greenguard Gold certification, which means very low amounts of VOCs will off-gas. The coils offer full lumbar support and are arranged to cradle your spine but are also stiff around the edge. The Luxe started off with an odd little lip around the edge of the mattress, but after a couple of months that went away. There’s no sag in the Birch Luxe, and I had none of the lower-back pain I associate with softer mattresses. The wool and latex top layers provide truly exceptional temperature regulation, and the pillowy top provides a nice bit of softness. (The pillow top is the main thing that separates this from the cheaper, not-Luxe model.)

Birch offers free shipping and a 100-night trial period, and all its mattresses come with a 25-year warranty. Birch offers an in-home setup and removal of your old mattress through LoadUp; details can be found on Birch’s website. The Luxe arrived completely compressed, and while it was small, it was definitely heavy. If your mattress is headed upstairs, or you’re not comfortable lifting bulky, heavy objects, we recommend going for the in-home setup option.

Coyuchi started out making organic bedding (its linen sheets are excellent), but this is the company’s first mattress and it’s an impressive first effort. 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 pocketed coil 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 finished product does not have any certifications beyond Greenguard Gold, but the material is undyed, which is great for anyone bothered b...
