Review: The Birch Elite Natural latex mattress kept me cool during a sweltering heatwave, but there are some big drawbacks I can't overlook

Review in brief

Birch by Helix is the brand behind some of the top organic mattresses you can buy online, and the Elite Natural is its most luxurious and durable offering — and boasts a price tag to match. A queen costs $3,749.33 at full MSRP, but regular Helix mattress sales mean you’ll usually pay around $2,999. It’s undoubtedly an investment, but is it worth it?

Along with my husband (and cat), I have been sleeping on a queen size Birch Elite Natural mattress for the past two months. Further below you’ll find my full review, including the test results that help paint a clear picture of its overall performance. But for a snapshot into how the Elite compares to the best mattresses of 2026 for all sleepers, here is my review in brief...

The Elite is a hybrid latex mattress made up of seven premium internal layers, which include individually wrapped steel coils, microcoils, organic cotton, sustainably sourced New Zealand wool and three different layers of GOLS certified organic latex.

Its organic materials result in a naturally breathable and cooling sleep feel. And, temperature-wise, I can honestly say I’ve slept pretty comfortably on this mattress throughout one of the hottest summers I can remember. (Yes, latex really is as naturally cooling as everyone says it is).

However, for an eco-friendly mattress packed with sustainably sourced organic materials, the glue-like smell during set-up was overwhelming.

Mattresses that have been compressed, rolled and placed in a box for delivery usually emit some kind of odor when unboxed. This is usually because the Volatile Organic Compounds (VOCs) inside the materials are being released into the air.

But because VOCs are found in chemicals, I wouldn’t have expected any off-gassing from the (largely) organic Elite. I opened a window and the smell dissipated quickly (and was entirely gone within a few days).

Smell aside, I found the Elite to feel firmer than the medium-plush tension that it’s marketed as. This shouldn’t have come as a surprise, as Latex is renowned for its buoyant and responsive sleep feel.

I felt it was closer to 7/10 for firmness, as opposed to the 5/10 rating from Birch. There is definitely a degree of sink-in support, but it feels as though the latex compresses under my weight as opposed to contouring around it.

I found support around the edge to be reliably sturdy, which means that you can safely sleep right up to the edge without feeling the mattress dip or collapse beneath you.

It’s responsive, which means you can move around easily on the Elite — that’s good news for people who move around a lot in bed.

Natural latex is an unyielding material made from the sap of rubber trees, so if you’re an average weight side sleeper looking for an organic mattress with plenty of sink-in, body contouring support — this isn’t it.

But for eco-conscious shoppers who are combination sleepers who like to shift positions frequently throughout the night, the Birch Elite Natural could be your perfect bed.

Price and trial

• A queen costs $3,749.33 at full MSRP, but regular sales mean you’ll usually pay around $2,999
• Comes with a lifetime limited warranty and 120 night sleep trial
• Sales range between 20% and 30% off, with the best deals reserved for major holidays

The Birch Natural Elite is a premium mattress that sits at the top of the brand’s lineup of (largely) organic beds — and therefore the most expensive. A queen costs $3749.33 at full MSRP, but you’ll usually pay $2,999 in the regular 20% off sale.

That sale runs throughout most of the year, rising to 25% and 30% off during major holidays, like the upcoming Labor Day mattress sales.

That brings a queen down to $2,624,53, which is the lowest price you can expect to pay. Right now, it’s $2,812 in an extended 4th of July sale.

Here’s how much you can expect to pay, per size:

• Twin: MSRP $2,498.66 (usually sold at $1,998.93)
• Twin XL: MSRP $2,749.33 (usually sold at $2,199.46)
• Full: MSRP $3,310.66 (usually sold at $2,648.53)
• Queen: MSRP $3749.33 (usually sold at $2,999)
• King: MSRP $4,498.66 (usually sold at $3,598.93)
• Cal king: MSRP $4,498.66 (usually sold at $3,598.93)

Plus, for an extra $372 at full MSRP for all sizes, you can get a specialist EcoCool cooling layer, made up of graphite strips to draw heat away from your body (more on that below).

Shipping is free and fast, while a white glove delivery service is potentially available — the fee/availability is dependent on your location. The Elite Natural comes with a 120 night sleep trial, which is plenty of time to know whether it’s the right fit for you.

If you do decide within that sleep trial that it’s not quite right, you can exchange or return the mattress after a 30 ‘break-in’ period. It’s worth flagging that the return/exchange service incurs a $99 return fee.

Those benefits are generous, but fall short in comparison to the Saatva Zenhaven, which, can cost as 'little' as $3,017 for a queen after a 15% off Saatva mattress sale, is perhaps the Birch Elite’s main competitor.

In contrast, the Zenhaven comes with a 365 night sleep trial and a free White Glove Delivery Service, which includes old mattress removal. Plus, returns are free.

Design

• The Birch Elite Natural is 15” tall and has 7 internal layers
• These include three separate perforated latex layers for comfort and support
• Organic materials including wool, latex and cotton come with high standard certification

The Birch Elite Natural is a 15” mattress that boasts seven internal layers, plus an organic cotton quilted cover that feels soft and cozy to the touch and fiberglass-free fire retardant protection.

Birch comes under the 3Z parent brand umbrella, which includes Helix, Brooklyn Bedding and Plank. Like the best mattresses in a box, these beds are assembled in Arizona before being compressed, rolled and boxed up for speedy delivery.

From the cover down, the Elite boasts a 3” thick quilted cover made from natural New Zealand wool and the first of three perforated GOLS-certified latex layers. Both wool and latex are naturally breathable, moisture-wicking fabrics that help keep you warm in winter and cool in summer.

Beneath the quilted cover and making up the top third layer of the mattress is a second softer layer of perforated latex. After that comes a 0.75” microcoil layer designed to contour around the touch points of the mattress.

Then comes the third, firmer layer of perforated layer of latex for stability. Combined together, the latex layers make up 4” of the mattress’ 15” height.

As a good hybrid mattress, underpinning it all is the 8” steel coil base, which is made up of hundreds of individually wrapped steel coils. These provide stability right up to the edge, as well as targeted lumbar support.

Comfort and support

• Mattress compresses rather than contours around the shape of your body
• Responsive surface is easy to shift positions on
• Feels firmer than the medium-plush that it’s advertised as

I slept on the Birch Elite Natural after sleeping on the DreamCloud Ultra Hybrid, a sumptuously soft but supportive luxury mattress with oodles of body-contouring support.

The Birch Elite is a completely different beast and, if I’m brutally honest, it was a while before I stopped craving the body hug feel of the DreamCloud.

In contrast, the Birch — despite being marketed as medium-plush with a firmness rating of 5/10 — felt too firm to me. I would place it closer to 7/10.

For context, I’m of average weight and I sleep predominantly on my side. So plenty of pressure relief around the shoulders, hips and knees is important.

But, initially, sleeping on my side felt like my shoulders were slowly being smushed up to my chin instead of being absorbed by the bed, leaving me with pain across my shoulder blades come morning.

Lying on my back also left me feeling fairly stiff and sore. As someone with recurrent lower back pain, I like my lumbar region to feel properly supported and weightless on the bed.

Instead, I could feel a slight gap between the base of my spine and the bed. This resulted in a build-up of pressure in the ‘S’ shape of my back.

If I could have handed the Birch Elite back after a week, I would have. But, as time went on, I was glad that I hadn’t. Yes, I personally prefer the gentle body cradling feel of some memory foam beds, but the responsiveness of the Birch’s latex layers have grown on me.

I can move around freely from position to position without feeling trapped (which has been a welcome feature during the recent heatwaves). I’m no longer waking up in pain. In fact, I now wake up feeling straightened out and refreshed.

Has the Birch softened up over time, or have I just got used to it? Probably a bit of both. But I now suspect going back to memory foam pillow tops might initially feel rather stuffy and restrictive in comparison.

Comfort and firmness is subjective and we all have our preferences. But I think the Birch Elite is best suited to eco-conscious combination sleepers who like to move around at night while sleeping on top of the mattress, as opposed to sinking deeply into it.

Comfort score: 2.5 out of 5

Delivery and setup

• The mattress comes in two separate boxes for ease of movement and set up
• Unboxing smell was surprisingly strong for a natural mattress
• The mattress expanded instantly, but brand says it can take up to 48 hours to establish its full shape

At 15” tall, the Birch Elite is a substantially tall bed. As such, Birch sends the mattress in two separate boxes (one bigger than the other). This is so that the box doesn’t become unmanageably big or heavy — but you’ll still need two people to manage both boxes.

Once my husband and I maneuvered the boxes upstairs, we set to unboxing the Elite. The mattress is separated into a thick base layer and then an insert layer. Once the base layer is cut out of its packaging and unrolled on your bed, you can unzip and pull back the top cover.

Then, once the insert layer is unboxed and unrolled, you can zip it into the base layer. It takes a bit of adjusting to make sure that the top layer aligns properly with the base layer, but it’s all fairly straightforward — if slightly more time consuming.

However, the payoff is that you get a luxuriously tall mattress packed with premium materials without compromising on the convenience of a mattress in a box.

Once set up, the mattress looked ready to sleep on immediately. However, Birch advises allowing two hours before applying any weight to it to ensure it establishes its proper shape and firmness, and cites that it could be between 24-48 hours until fully expanded.

As an all-natural (and mostly organic) mattress, I was expecting zero off-gassing from the Birch Elite. Off gassing is the release of Volatile Organic Compounds (VOCs) from chemicals into the air.

The smell was glue-like and pungent, but quickly dissipated once I opened the window.

Performance

• Some motion transfer means that restless couples could feel some disturbance
• Excellent support around the edge of the bed means you can sleep right up to the edge
• Breathable materials mean it boasts excellent temperature regulation

As well as my subjective experience of sleeping on the Birch Elite Natural mattress, I performed a series of objective tests that allows me to give a 360 view of its performance. During testing I focused on three areas of performance: temperature regulation, motion isolation, and edge support.

Temperature regulation is a term to describe how effectively a mattress dissipates body heat, rather than trapping it.

Strong temperature regulation doesn't necessarily mean it's actively cooling, it means that it keeps the temperature consistent. On the flip side, a mattress that holds on to heat can lead to night sweats and night time awakenings.

Motion isolation is essentially how well a mattress absorbs movement across the surface of the bed, which is why it's an important feature for couples.

A mattress with strong motion isolation means you're unlikely to be disturbed by movement elsewhere in the bed. However, a mattress with poor motion isolations means you're likely to feel every toss and turn.

Finally, edge support refers to how sturdy the perimeter of the mattress feels. Strong edge support is important for bed sharers or anyone else who might like to sleep right up to the bed's edge.

It's also important for those with mobility issues who need to safely sit before getting in or out of bed.

Motion isolation

In order to test the motion isolation of a mattress during our at-home testing process, I measured 32” down from the top and 12” in from the left side of the mattress.

I marked this spot with a piece of black tape before placing an empty wine glass on it. On the opposite side of the mattress I measured 32" down and 12" in from the side and marked this spot with black tape.

I then measured 24" in the air above this second spot, before dropping a 10lb kettle bell. This test mimics someone getting in and out of bed. After the initial drop, the wine glass wobbled but didn't fall over. I repeated this process a further four times, during which it fell over once.

This mirrors my experience of sharing the bed with my husband. I do feel some motion across the surface of the bed when my husband gets in and out of bed, but it isn't pronounced enough to wake me. However, I suspect this would be a different story for light sleepers.

Motion isolation score: 2.5 out of 5

Temperature control

To asses the temperature regulation of a mattress at home, I lie on my side for fifteen minutes. I tested the mattress during an unseasonably hot spring and summer, so my bedroom felt warmer than usual.

Image 1 of 3

Despite this, the mattress felt cool beneath me throughout the fifteen minute testing period. Again, this test reflected how I felt during the two months of sleeping on it, the majority of which was during heatwaves.

During hot evenings, I only needed to kick a leg out or roll over to feel the coolness of the latex (this felt like flipping your pillow over to feel the cool side). Although the Birch Elite is not a specialist cooling mattress, it did an excellent job of helping me sleep comfortably cool.
However, for very hot sleepers, there is also an option to upgrade to an EcoCool layer for an extra $372 for all sizes. This is a layer of graphite ribbons that actively draw heat from the body and dissipates it across the surface of the bed.

Temperature control score: 4 out of 5

Edge support

To measure a mattress' edge support at home I initially sat on the edge to assess how it felt beneath me; comfortably sturdy. I could safely plant both feet on the floor without feeling myself sliding off.

In order to assess its edge support objectively, I then measured a spot 30" across and 3" in from the foot of the mattress and marked this zone with tape. After placing a 56lb weight on this drop zone, the weight initially sank 2" and felt secure on the bed's edge.

After leaving the weight for 5 minutes, the weight has sunk to 3.5" but remained secure on the edge. Next, I measured 32" down and 3" in from the side of the mattress. Again, the initial sink here was 2" and sank to 2.5" after leaving it in situ for 5 minutes.

Having slept on the Birch Elite for the past two months, I feel as though edge support is one of the areas where it really shines. I can safely sleep right up to the bed's edge without feeling as though I'm slowly sinking or sliding off.

Edge support score: 4 out of 5

Customer reviews

• Launched in 2025, the Birch Elite has 4 stars after 48 reviews
• Positive reviews cite its naturally cool sleep feel, back support and overall comfort
• Negative reviews claim it feels firmer than advertised

Since its launch last year, there are only 48 reviews of the Birch Elite Natural, with an average 4 out of 5 stars. Among the positive reviews, customers laud its overall comfort and temperature control. "Extremely comfortably, supportive and cool," reads one review.

Others rate it highly for its back support, crediting it with helping them stay asleep all night and wake up pain free.

Of course, comfort is subjective and other reviews complain that it's firmer than advertised, with one couple saying it left them with a tingling sensation along their arms and legs after sleeping on their sides.

Should you buy it?

Who should buy it and why?

✅ Hot sleepers: Wool, cotton and natural latex are all naturally breathable materials that wick away moisture while you sleep, which translates to excellent temperature control.

✅ Eco-conscious shoppers: While not 100% organic, the Birch Elite is packed with premium GOLS and GREENGUARD GOLD certified materials for clean, non-toxic sleep.

Who shouldn't buy it and why?

❌ Side sleepers who favor a body contouring feel: Thanks to its latex layers, the Birch Elite compresses beneath your weight as opposed to contouring around it, which can lead to a build up of pressure along your shoulders and hips.

❌ Restless bed-sharers: Although support around the perimeter of the mattress means you can sleep right up to the bed's edge (which is great news for space-saving couples), average motion isolation means restless sleepers might feel movement from their partner.

Is it worth it?

The Birch Elite is made from a raft of premium natural and (largely) organic materials, including New Zealand wool, GOLS certified organic latex, organic cotton and steel coils.

The combination of quality materials and craftsmanship means that you're buying a durable mattress that could potentially last you decades.

If well looked after, latex mattresses could last up to 20 years. So, while you will pay in the region of $3,000 for queen, that investment could pay off in the long run.

Of course, it's only a worthwhile investment if you actually find the mattress comfortable. For me, the Birch Elite isn't quite plush enough to provide the body contouring support I personally crave as a side sleeper.

However, body type and weight impacts mattress firmness levels, so heavier side sleepers might find it more suitable. (For average weight side sleepers, I would recommend the Awara Classic Hybrid instead, an organic mattress with a softer feel).

On the flip side, heavier back and stomach sleeps might find the Birch Elite too soft. In that instance I would recommend the Saatva Zenhaven instead, a dual-sided premium latex mattress with firmer support.
