Birch Mattress Overview

Birch is an eco-friendly mattress-in-a-box that’s made with natural latex and organic cotton and wool. It has a base layer of individually wrapped coils and comfort layers made with chemical-free latex foam.

Although Birch only sells one mattress, customers have some customization options. If you prefer a firmer mattress, the original Birch is the way to go. Those who want a softer mattress with a plush comfort layer can order a pillow top cover. This addition is what makes it one of the best pillow top mattresses!

We tested the Birch mattress without this pillow top cover. Is this the right choice for you? Keep reading to find out!

Birch Mattress Firmness and Feel

Now, let’s check out the Birch’s overall feel and firmness level.

How Firm is the Birch Mattress?

We tried the Birch without the pillow-top and thought it was close to a 7/10 in terms of firmness. The wool layers and latex are somewhat soft, but once you push down into the mattress, you hit some firmer support layers. This makes the mattress slightly firmer than average.

Sleeping On The Birch Mattress

Back sleeping, the Birch is a good fit for me. My hips sink into the wool and latex layers, but they don’t sink in too far. In addition, I feel the latex foam pressing up into my lumbar area and preventing lower back pain.

Birch Mattress - Back Sleeping

When I am side sleeping, the mattress is too firm for me. If you are a side sleeper, it is worth choosing the pillow-top. This will give you much better pressure relief on your shoulders and hips. In fact, we think the pillow-top version is best for side sleepers.

Stomach sleeping, the Birch without the pillow-top is very supportive. I feel well-aligned, and the mattress does not allow me to bow in at the hips. It could be a great mattress for stomach sleepers.

What Does the Birch Mattress Feel Like?

The Birch has a feel that you find with most latex mattresses. It is very bouncy. The combination of latex and coils make the mattress very responsive, so it is easy to move around. You should sleep on top of the mattress without sinking in too far.

However, if you do decide to go with the pillow-top, this will give the mattress a plusher feel on top.

Average Weight Sleepers – 130lbs – 230lbs

Average weight back sleepers should feel very comfortable on the Birch mattress. The latex foam provides nice contouring for the lower back, and the latex layers allow hips to slightly sink into the mattress.

Those who weigh between 130 and 230lbs may find the Birch mattress feels too firm while side sleeping. People who prefer this sleeping position may prefer the Birch mattress with the optional pillow top, because this adds an extra layer of plush pressure relief.

Stomach sleepers should feel well supported on the Birch mattress without the pillow-top. The firmness level prevents hips from dipping too far into the top layer, which keeps the body in alignment. The additional pillow-top, however, could make the bed feel too soft for stomach sleeping.

Heavyweight Sleepers – Over 230lbs

Heavyweight back sleepers should find the Birch mattress offers a great deal of comfort. The firm construction can easily support heavier weights, and it allows hips to sink into the top layer the right amount.

While side sleeping, heavyweight sleepers may find the Birch mattress adds too much pressure to shoulders and hips. Generally, side sleepers will want a mattress with a substantial comfort layer that can ease pain on pressure points. Heavyweight side sleepers may want to consider getting the additional pillow-top for more comfort.

The Birch mattress may not be a great fit for heavier stomach sleepers. The mattress isn’t supportive enough to keep the body in proper alignment. Instead, they should take a look at the best mattresses for heavy people.

Lightweight Sleepers – Under 130lbs

Lightweight sleepers should find the Birch is very comfortable while back and side sleeping. In fact, we named it one of the best mattresses for teenagers. Lightweight people aren’t likely to sink deeply into the initial comfort layer, so it should provide enough comfort and support. The Birch may not be a great fit for lightweight stomach sleepers because they may not feel the full support of the coils underneath.

Birch Mattress Construction

What’s the Birch mattress made with, exactly? Let’s take a look at its construction, layer by layer.


The cover is made of organic cotton and feels soft, stretchy, and breathable.

Comfort Layers

There is a layer of wool underneath the organic cotton cover, which helps keep the top of the mattress soft and breathable. It also makes the Birch a flame retardant mattress, which should give you peace of mind.

Birch Mattress - Construction

Beneath that sits a layer of 100% organic wool, which adds a bit of comfort and pressure relief. Next, you’ll find a layer of ventilated Talalay latex for even more pressure relief. Like most latex, this layer feels responsive and allows people to sleep on top of the mattress rather than “in” it.

You can choose to add a pillow-top to your Birch mattress. The pillow-top adds 3” of comfort, so you should feel better pressure relief on your shoulders and hips. With this addition, it is one of our top-rated pillow top mattresses.

Support Layer

The support layer consists of individually-wrapped coils, which are highly supportive, durable, and breathable. They rest on a base layer made of wool batting.

Mattress Height

The Birch mattress is 11” tall. The additional pillow top will add another 3” to the height of the Birch mattress.

Birch Mattress Performance

Now, let’s take a deeper look at the Birch mattress’ performance. Read on to learn about its cooling features, motion transfer, and edge support.

Sleeping Hot or Cold

The Birch should be a cooler sleeping mattress. The Birch is a hybrid mattress, and the coils promote airflow through the mattress, making it very breathable. The wool and aerated latex also add some breathability to the top of the mattress. Hot sleepers should take a look at the Birch without question.

Motion Transfer

When it comes to handling motion transfer, latex and coils are not really the best materials. If you want a mattress to cut down on the disturbances made by a sleeping partner, memory foam or some soft foam is usually a better choice.

To test out the Birch’s motion isolation capabilities, I placed a glass of water on the mattress. When I pressed into the other areas of the mattress, I saw quite a bit of disturbance. Also, I laid down on the mattress while Marten got in and out of bed and mimicked the movements of another sleeper, and I definitely felt his movements on my side of the bed.

If you want a mattress for couples, it is worth noting you could see some motion transfer on the Birch.

Edge Support

If you are looking for a couples mattress, you should also think about edge support. Will you be able to sleep toward the edge of the mattress, or will you have to sleep closer to the middle?

When I sit on the edge of the Birch, I don’t feel like I am going to pitch forward. I feel secure enough to lean over and tie my shoes. I also feel like I can lie down close to the edge without feeling like I am going to fall off.

People can see the good edge support in the photo below.

The Birch is made with high quality and durable materials that shouldn’t sag over time. Because of this, we expect it to last 7-10 years.

It’s common to notice a slight smell when opening a new mattress. Because the Birch is made with all-natural materials, however, we did not smell any chemical odor. Off-gassing should not be an issue with this mattress.


The only component that could possibly create sound is the coil layer, and it was not squeaking when we tested the Birch mattress. Overall, we think this will be a quiet mattress.


Couples looking for one of the best mattresses for sex should consider the Birch. This mattress is very firm and bouncy, making it easy to move around and change positions. Partners will feel like they are lying on top of the mattress rather than inside it.

How Does The Birch Compare To Other Mattresses?

There are tons of bed-in-a-box brands out there. Before pulling out your wallet, it’s a good idea to check out some of the mattress’s competitors. Let’s see how Birch stacks up in comparison to other popular options.

Birch Mattress Vs. Avocado

Both the Birch and Avocado mattresses are made with organic materials, so they’re great options for those who want to be green. We found the Avocado mattress to be slightly firmer than the Birch, making it a better option for stomach sleepers.

The side of the Avocado mattress.

In terms of construction, the Birch and Avocado are very similar. Both options have layers of coils and memory foam. The base models are both 11” tall, with the option to add an additional pillow top. The Birch pillow top is more plush than the Avocado, making it a great option for side sleepers. We found the Avocado mattress is better at isolating motion, while the Birch has better cooling features.

The two mattresses have similar price ranges,  but the Birch is slightly more affordable. A queen-size Avocado mattress costs $1,799 and a Birch of the same size costs $1,499.

Birch Mattress Vs. My Green Mattress

Both the Birch and My Green Mattresses are great picks for those who want a bed made with non-toxic materials. Those looking for a variety of options may want to consider My Green Mattress, because they have all-foam, latex-free, and hybrid mattresses.

My Green Mattress

My Green Mattress’ Natural Escape is the most similar to the Birch because it is made with coils and memory foam. Both mattresses feel responsive and bouncy, but we found the Birch mattress feels more supportive. The Birch has better edge support and cooling features, while My Green Mattress is better at isolating motion.

My Green Mattress is slightly more affordable than Birch, with a queen-size Natural Escape coming in at $1,399.

Now, let’s check out the answers to some of the Birch Mattress’ most frequently asked questions.

How firm in the Birch mattress?

In our testing, we found the Birch mattress to be slightly firmer than average, making it a good fit for back sleepers.

Can you flip the Birch mattress?

No, you cannot flip a Birch mattress. It is designed with coil layers on the bottom and memory foam on top. Flipping it would alter the intended firmness and feel.

What if I don't like my Birch mattress?

If, during the initial 100-day sleep trial period, you decide you don’t like the Birch mattress, you can return it for a full refund. Birch Mattress asks its customers to test out the mattress for at least a month before returning, because it often takes people several weeks to determine whether it’s the right fit for them.
