Since launching in 2019, Birch has built a strong reputation for their mattresses and bedding products made from sustainably sourced and eco-friendly materials. They offer three mattresses: the Birch Natural Mattress, the Birch Luxe Natural, and the Birch Kids Natural. All three options are latex hybrids.
Throughout the mattress, Birch demonstrates a commitment to quality design and materials. Checking in at 11 inches tall, the Birch Natural Mattress has organic cotton and wool, natural latex, and sturdy pocketed steel coils. This construction gives the mattress a bouncy feel with robust edge support, light cushioning, and excellent temperature regulation.
Our testing team put this mattress through an extensive analysis to find its strengths and weaknesses. We’ll cover those and get into the details of the construction, pricing, and key purchase information of the Birch Natural Mattress to help you decide if it’s the right fit for you.

Testing Team Takeaways
To test the Birch Natural Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

Showers before bed
The Birch Natural was a great bed. The latex had a good amount of give to take the pressure off my hips and shoulders, but it didn’t hug as well as memory foam does. The latex and coils were both strong enough to keep me supported and sleeping comfortably, and the firmness was pretty middle-of-the-road. I can see the Birch being a hit with a wide range of people.

I found the Birch Natural Mattress to be both supportive and springy. I felt that my pressure points were well cushioned, and I was able to move around with ease, making for a restful night. I found back sleeping to be excellent on this mattress. The edges are slightly stiffer and provided additional support that I appreciate when shifting sleep positions.

As someone who sleeps hot and moves around a lot in my sleep, I appreciated the cooling natural materials in the Birch Natural Mattress. It’s also very easy to move around on and provides a floating feeling that I’m very fond of.

Side Sleepers
Our testing found that the Birch Natural Mattress performed well among a large number of side sleepers. It got the highest marks from side sleepers who weigh over 130 pounds.
Although latex isn’t known for deep contouring, our team was impressed by how well the Birch Natural Mattress cushioned the hips and shoulders when side sleeping. Properly supporting these high-impact areas is essential for spinal alignment.
A few people under 130 pounds wanted more cushioning, and a few over 230 pounds felt there was a bit too much sink. In the end, though, no one said it was a dealbreaker. That said, side sleepers who know that they want a deep hug or contouring from a mattress may be better off with a memory foam mattress.
Back Sleepers
When put through testing, the Birch Natural Mattress delivered excellent results for back sleepers across different body weights. Its resilience and bounce kept back sleepers in a neutral position without undue sinkage under the lower back and hips.
At the same time, the gentle cushioning from the latex and wool accommodated the curvature of the back. This earned the Birch Natural Mattress high marks for both comfort and support. By a small margin, back sleepers between 130 and 230 pounds gave the highest ratings to this mattress.
Stomach Sleepers
Although the Birch Natural Mattress can be effective for stomach sleepers of any weight, we found that it was the best match for those over 130 pounds. Our testers of that weight felt that the mattress had the right balance of cushioning and bounce to keep them in a flat and even position. Some sleepers over 230 pounds had trouble with the firmness of the bed, as it was a bit too soft for them to feel supported enough.
Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
Motion Isolation
6
/ 10
The Birch Natural has pretty significant bounce, so motion isolation isn’t one of its strong points. You won’t feel every movement from your partner if you share the bed, but you’ll definitely notice if they’re tossing and turning. – Jackson
The Birch Natural Mattress definitely has more bounce than contouring, which in our testing lab meant more motion transfer. Vibrations from movement on one part of the bed could be felt at least lightly on other parts of the bed.
For most couples, motion transfer on the Birch Natural Mattress isn’t enough to create a significant problem. But if you’re easily awoken during the night, you may encounter more sleep disruptions from your bed partner’s movement when sleeping on the Birch Natural Mattress compared to an all-foam model.
Pressure Relief
6.5
/ 10
When side sleeping I found the Birch Natural Mattress “just right” as it was neither too soft nor too firm. My hips and shoulders felt equally supported. The back sleeping position was particularly good though! – Mary
The Birch Natural Mattress offers effective pressure relief for many sleepers, but it may not be the top option for people who want deep contouring around their body.
The wool and latex layers of the Birch Natural Mattress lightly cradle the joints and heavier parts of your body, but these materials do not hug you closely. In most cases, the cushioning from the latex is enough to relieve pressure, but it may be lacking in this category for people with very sharp pressure points.
Temperature Control
8.5
/ 10
I often wake up from overheating, but that was not a problem with the Birch Natural Mattress thanks to its moisture-wicking wool, natural latex, and pocketed coils preventing heat buildup and enhancing airflow. – Danny
Our testing team found that the Birch Natural Mattress demonstrated excellent temperature control. It has several components that promote cooling and temperature neutrality. Wool and cotton are highly breathable, helping wick moisture and dissipate heat. Latex does not heat up the way foam materials do, and the coil support core enables plenty of ventilation.
In addition, the responsiveness of the mattress keeps you from sinking in too far. As a result, airflow can reach your skin and help cool you down. All of these factors make the Birch Natural Mattress a leading choice for hot sleepers.
Edge Support
8.5
/ 10
The Birch Natural Mattress has pocketed coils that are thicker and sturdier around the edges, providing amazing edge support. Getting on and off the bed was super easy! The extra support also made me feel like I had more room. – Mary
The Birch Natural Mattress offers solid edge support that comes from the bounciness of its materials and its thick layer of pocketed coils. The coils are reinforced around the perimeter to give the mattress a more stable feel when sitting or lying down near the edge.
Ease of Movement
8.5
/ 10
I found it incredibly easy to move around on the Birch Natural Mattress. The bouncy latex layer feels buoyant and springy. – Danny
The Birch Natural Mattress keeps you from feeling stuck in one position. Our testers observed that, thanks to its responsive materials like latex and coils, you can easily adjust your sleeping position, roll over, or get up out of bed.
The ease of movement on the Birch Natural Mattress makes it a good fit for combination sleepers and anyone else who prefers to feel like they are sleeping on top of the bed rather than “in” the bed.
Off-Gassing
8.5
/ 10
When we unboxed the Birch, it had a bit of smell to it, but it wasn’t that bad. It’s also a totally different odor from memory foam – latex just isn’t stinky in the same way, it feels more natural. If your bedroom is decently ventilated, you probably won’t notice much of a smell after a few hours. – Jackson
The Birch Natural Mattress only has a light smell after unboxing, and it’s far less bothersome than the chemical smell that can come from foam materials. While you may detect some minor scent from the latex, it’s not harmful, especially since this mattress contains organic and natural materials. Any smell should be gone within a few hours or at most a day as long as your bedroom has good ventilation.
The Birch Natural Mattress is a latex hybrid that takes advantage of the benefits of pocketed coils and several natural materials to promote a balance of cushioning, bounce, and stability. It is 11 inches tall and has a firmness level of medium firm (6).
The cover is made with cotton that is fair-trade and certified organic by the Global Organic Textile Standard (GOTS). Directly under the cover is a fire barrier of organic wool batting.
Beneath that, there is another layer of organic wool, which adds softness with only minimal contouring. Wool has excellent moisture-wicking properties, and its breathability helps keep the surface of the mattress cool.
Under the wool is a layer of natural latex, which provides gentle contouring and considerable bounce. Latex resists heat retention, further contributing to the cool temperature of the Birch Natural Mattress. The latex has earned certifications from institutions like OEKO-TEX and the Eco-Institut that demonstrate that it does not emit chemicals known to be harmful.
The support core is composed of individually pocketed metal coils. Thicker coils reinforce the perimeter to increase edge support. Under the coils, a bottom layer of organic wool acts as a fire barrier.
