The Pros and Cons

✅ Pros

• Edge Support: This mattress has good edge support, meaning you can lie near the edge securely, and feel supporting sitting there to get ready in the morning.
• Responsiveness: The natural responsiveness of latex really comes through in the Birch mattress. It was both easy and comfortable to move on the mattress surface.
• Social Impact: The Birch collection of sleep products is made from natural and organic materials, great for both your health and the Earth.
• Durability: Backed by a 25-year warranty, this mattress will likely last for many years thanks in part to its strong coil system.

❌ Cons

• Motion Transfer: We noticed the Birch mattress didn’t isolate motion very well and was squeaky when we had our tester get in and out of it, both of which could be problematic for couples who don’t want to disturb each other.
• Cost: A lot of care went into getting the mattress materials for Birch and the price reflects that. This is more of a luxury buy and may not appeal to budget shoppers.
• Smell: While the Birch Natural doesn’t come with the common off-gassing smell that other bed-in-box mattresses come with, we could smell the natural materials when unboxing.

Motion Transfer

Sleeping with a partner, pet, or kids can mean constantly getting woken up by their tossing and turning, midnight snack cravings, or bathroom breaks. You want a mattress that won’t jostle you as your bed partner moves or gets up. The Birch mattress didn’t do so well in this category, likely due to the coiled support layer. If you sleep with a partner, consider the Helix Midnight, which scored higher in this category.

Durability

A mattress is an investment you should enjoy for many years to come. A mattress with good durability is sure to last its entire lifespan with proper care. This is especially important for plus-size sleepers or those who sleep with a partner, as their mattresses tend to wear down more quickly. Thanks to their naturally sourced and handmade materials, the Birch mattress is built to last, earning a perfect 10/10.

Spine Alignment

You’ve probably heard that bad posture can lead to nerve constriction and poor digestion, so you should sit up straight. Well, posture is just as important when you’re lying down as when you’re standing up. Your mattress should allow your spine to be straight and maintain its natural curve as you sleep. The Birch mattress’s latex layer allows your spine to stay straight while it relieves pressure points.

Explore our top picks for the best latex mattresses. 

Pressure Relief

We measure pressure relief capabilities using a special pressure map tool. If an area is blue and green it means it provides excellent pressure relief. Spots with yellow and red indicate an area of pressure buildup. As you can see below, the map was all blues and greens when our heavier tester lay on their back and side.

Our lighter tester also had blue and green areas when they lay on their back. However, when we had our lighter tester lie on their side, we noticed slight pressure buildup in their hip area. If you are a lighter sleeper who tends to sleep on their side, you may want to consider one of our best mattresses for side sleepers, like the Saatva Classic.

Firmness Level

Birch Natural has a firm feel, landing at about an 8/10 on the firmness scale. This firmness level is preferred by those that want more support than a plush mattress can give. It had a bouncy, elevated feel when we lay on it. For those looking for a plusher mattress, consider the Birch Luxe Natural Mattress, which includes two additional comfort layers.

Check out our top picks for the best firm mattresses and best extra-firm mattresses.

Sleeping Position Compatibility

The Birch Natural Mattress works well for three sleeping positions:

• A good mattress for back sleepers and good mattress for stomach sleepers: Sleep on top of the mattress rather than in it, which helps with alignment.
• A mattress for combination sleepers: Easily change positions on its sleep surface.

We don’t recommend the Birch Natural for side sleepers, primarily because of its 8/10 firmness. Side sleepers need their hips to sink into the surface a bit to avoid pressure buildup, which is why soft, medium, or medium-firm mattresses usually match up best for that sleeping position.

Check out our roundup of best mattresses for side sleepers.

Temperature Regulation

Birch has a few temperature regulating layers, including latex foam and wool batting. While latex is a naturally cool material, the cotton and wool layers bring too much insulation to be completely cooling. We gave this mattress an 8/10 for cooling since it’s slightly above average cooling mattresses.

Explore our top picks for the best mattresses for hot sleepers.

Which Body Types Does Birch Support?

There is a 1,000-lb weight capacity for Birch, meaning it can support heavier people. Latex foam is one of the most durable, supportive mattress materials around.

Compatible Foundations

A foundation is not required for the Birch mattress, but it is recommended. We prefer a bunkie board, boxspring, or a slatted base with slats no wider than 5″ apart. The slats should also be firm, flat, and thick.

A Peek Inside

There are four core layers to the Birch mattress alongside a natural and organic cover and fire resistant layer. The materials inside are GOTS, OEKO-TEX, eco-INSTITUT, and Rainforest Alliance certified, meaning this mattress is made with certified natural and organic materials.

What’s Unboxing Like?

The Birch mattress comes rolled up in a tall cardboard box, delivered to your door. It took our testers two minutes to unbox and took its full shape quickly. While we didn’t notice any off-gassing smells, we did smell the natural materials used in the mattress, which may be unappealing to those with a sensitive nose.

Using Your Trial Period

You have 100 nights to try your new Birch mattress and make a free return if you don’t like it. That means you get to take three months to really make sure this bed is for you. They only ask that you give yourself up to 30 nights to break in your new bed first.

Warranty Breakdown

Because latex is such a durable material, you get a 25-year warranty with your Birch mattress. You get full coverage for your first 10 years and prorated coverage for the last 15. This warranty covers

• Impressions deeper than 1″
• Physical flaws resulting from proper handing
• Manufacturing defects

• Fill out a contact form on their website.

How Do Returns Work?

You can return Birch for free during your sleep trial. You don’t even have to worry about shipping it back. Birch will either handle donating your mattress to a charity of your choosing or they’ll recycle it. Your refund will be issued after the donation or recycling process.

Is Birch Natural for You?

Let’s recap the pros and the cons of Birch to help you decide if this is the right mattress for you.

Birch is a bed-in-a-box mattress made with organic and natural materials. This natural mattress is great for eco-friendly people, heavier sleepers, and all sleep positions. You get 100 nights to try it out and a 25-year warranty if you decide to keep it.

You might want to keep shopping if you find yourself on a budget or if you tend to sleep hot. It’s also not a great mattress for those that sleep with a partner and want a bed with motion isolation. If you check either of those boxes, consider checking out the Tuft & Needle Mint mattress.

Birch Mattress Comparisons

Birch Natural vs. Avocado

Criteria	Birch Natural	Avocado Green
Mattress Advisor Score	9.2/10	8.5/10
Firmness	Firm: 8/10	Medium-Firm to Firm: 7/10 (6/10 with European pillow-top option)
Material	Latex Hybrid	Latex Hybrid
Who’s It Best For?	Those that want good edge support All sleeping positions Those that want a long-lasting mattress	Those with back pain Those that want a longer trial period Combination sleepers

The Birch and Avocado mattresses are both organic mattresses with latex hybrid constructions. They both work well for back sleepers and stomach sleepers, but side sleepers should opt for the Birch because of its pressure-relieving qualities. However, if you are prone to shifting between positions in the middle of the night, we recommend the Avocado Green mattress.

With Avocado’s strong spine alignment scores, it’s a good option for those with back pain; however, Birch outperformed Avocado in motion isolation, making the Birch a better option for those that sleep with a partner. Additionally, while both mattresses performed pretty well in terms of durability, the Birch obtained a perfect 10/10, making it a great long-lasting mattress.

Birch Natural vs. Awara

Criteria	Birch Natural	Awara
Mattress Advisor Score	9.2/10	8.8/10
Firmness	Firm: 8/10	Medium-Firm: 7/10
Material	Latex Hybrid	Latex Hybrid
Who’s It Best For?	All sleeping positions Those who want a durable mattress People with back pain	Hot sleepers Couples People with allergies

The Birch and the Awara mattresses are made using natural and organic materials. While the Awara works best for back and stomach, the Birch works for any sleeping position. If you sleep with a partner, both mattresses have high responsiveness scores; however, the Awara scored better for motion transfer, meaning you are less likely to feel your partner move around in the middle of the night.

The Birch comes with a 100-night sleep trial and a 25-year warranty, while the Awara comes with a 365-night sleep trial and a lifetime warranty. If these additional perks drive your purchasing decisions, you may consider the Awara.
