The Birch Natural, created by bed-in-a-box brand Helix, offers a natural mattress alternative by combining latex with organic cotton and wool.
Our in-depth review of the Birch mattress guides you through each layer, breaking down the sustainable materials that make up the bed. We also discuss how this organic mattress performed in categories like pressure relief, cooling, and support so you can decide if this bed’s right for you.

Who We Recommend the Birch Natural For:
- Environmentally-conscious folks – People seeking a more sustainable product should find a match in the Birch’s natural latex construction, which is topped with organic cotton and wool. The mattress also boasts numerous environmental certifications for its eco-friendly design.
- Sleepers who like bounce – The Talalay latex in the comfort layer is springy, and works well with the individually-wrapped coils below. This gives the bed a good level of bounce, making it easier for sleepers to reposition.
- Fans of hybrid mattresses – The Birch Natural offers the best of two mattress types by combining latex with coils. This hybrid construction helps the Birch check off many boxes like support, pressure relief, and cooling, so sleepers looking for a versatile mattress should be pleased.
Who We Don’t Recommend the Birch Natural For:
- Folks who want a plush, soft feel – This mattress is slightly firmer than average, which should be great for back and stomach sleepers who want extra support and spine alignment but not so much for those seeking a softer bed. However, the company does offer a plush topper which can dampen some of the firmness.
- Co-sleepers with restless partners – The Birch Natural offers lots of bounce, which means it may not perform as well when it comes to motion isolation. Sleepers who bunk with a light sleeper or couples concerned about disturbing their partner may want a mattress made with foam for better motion isolation.
First Impressions: Firmness & Feel
Firmness Scale: 6.5/10 (Medium Firm)
Please remember that firmness is a subjective characteristic and your shape will dictate how you experience a bed. A heavier person whose weight can more easily push through softer comfort and support layers may experience a bed as softer than a lightweight person. The way you are shaped could also play a role here. Consider your weight, shape, and size when evaluating firmness scores.

When measuring a mattress’s firmness, we rate how it feels on a 1-10 scale with 1 being the most soft. We rated the Birch Natural a 6.5 out of 10, which makes it just slightly firmer than medium-firm. The versatility of this firmness, especially when coupled with the soft Talalay latex, level should work well for a variety of sleepers, but especially average-weight to heavyweight back and stomach sleepers.
However, lightweight sleepers may find that they don't sink enough to enjoy the same level of cushioning, and are probably better off with a softer mattress that’s closer to a 5 out of 10 in the firmness scale.
How Does It Feel?
When you first lay on the bed, you’ll notice the bounce straight away – this is the latex and coils doing the talking. Once you settle in, you should expect the wool and latex to cradle your shape, while the coils push back against your spine to hold it in alignment.
Talalay latex is processed in a way that results in a more consistent and springier foam that is quick to respond to pressure and feels light and airy.
What We Like About the Birch Natural
- No harmful chemicals – The Birch Natural is all-natural and made without any harmful chemicals. This bed has Greenguard Gold and GOTS-certified materials which ensure the materials are free of toxic materials like pesticides and flame retardants.
- Naturally cooling – A combination of organic cotton and wool, naturally breathable latex, and individually-wrapped coils should keep this bed cool as you sleep.
- Plenty of bounce – The latex combined with the coils provide a good bit of bounce, making it a good pick for sexually-active couples and those who reposition often.
Our Birch Natural Complaints
- Little sinkage – Those who like to feel deeply cradled as they sink into a mattress may not care for this firmer bed.
- Too much motion transfer – Those who sleep with restless partners may not like this bed because they may be distributed by their partner’s movements throughout the night.
- May need a pillow topper – Without a plush, soft pillow topper, this mattress may be too firm for some sleepers.
Testing the Birch Natural Mattress: How it Performed
How did the Birch Natural stack up in our testing? To determine its performance, we tested this mattress for side, stomach and back sleepers to better understand which sleep positions that this mattress is best suited for. Body weight can also affect how you experience a mattress so we also took this factor into consideration. Finally, we examined qualities like supportiveness, responsiveness, and motion isolation to decide if it’s a good fit for couples.
Sleeping Positions for Different Body Types
According to Helix, the Birch Natural mattress can hold 500 pounds a side or 1,000 pounds total. Its firmer feel combined with this weight capacity should make it a good fit for heavyweight sleepers, although those who weigh more than 300 pounds may want a mattress that’s specifically designed for plus-size sleepers.
Weight | Side Sleepers![]() | Back Sleepers![]() | Stomach Sleepers![]() |
---|---|---|---|
Lightweight Sleepers (-130 lbs) | ★★☆ | ★★★ | ★★☆ |
Average-Weight Sleepers (130-230 lbs) | ★★★ | ★★★ | ★★★ |
Heavyweight Sleepers (+230 lbs) | ★★☆ | ★★★ | ★★☆ |
Side Sleepers
- Lightweight Sleepers – This mattress should be a great fit for most lightweight side sleepers. Latex is a naturally pressure-relieving material, which helps cushion these sleepers hips and shoulders. However, some petite sleepers may want a softer bed for even deeper pressure relief.
- Average-weight Sleepers – The Birch should work well for average-weight sleepers who rest on their side, as the coil base helps maintain spine alignment while the latex layer relieves pressure.
- Heavyweight Sleepers – Heavyweight side sleepers should sink into this mattress more than the other weight groups, helping them get ample cushioning for sensitive spots. However, some plus-size sleepers may sink too far into the mattress, which may cause them to bottom out to the coils.
Side Sleepers
- Lightweight Sleepers – Back sleepers on the lighter side, should sleep well on this mattress. They should feel lightly cradled by the mattress while the coil base provides ample support.
- Average-weight Sleepers – Average-weight back sleepers should enjoy how the latex contours to their lower back, while the coils support the hips for optimal spine alignment.
- Heavyweight Sleepers – Most heavyweight back sleepers should find that this mattress keeps their spine well-aligned. The coils will likely also support their weight as the latex wraps them comfortably.
Stomach Sleepers
- Lightweight Sleepers – The soft contouring of the latex should provide comfort for most petite stomach sleepers, while the coils keep their hips supported. However, some of these folks may want a slightly softer mattress for deeper cushioning for the chest and shoulders.
- Average-weight Sleepers – The firmness of the Birch Natural should allow average-weight stomach sleepers to experience the best of both worlds. The Talalay latex should cushion their front, while the bottom coil layers keep the hips raised and spine aligned.
- Heavyweight Sleepers – The Birch’s firmer feel should work well for most heavyweight stomach sleepers. However, those who weigh 300 pounds or more may want an even firmer bed for greater support, as they may sink too deeply into this mattress and experience spine misalignment.
Pressure Relief & Pain
A bed with good pressure-relieving capabilities allows heavier areas of the body to sink into the mattress so you can sleep comfortably without aches and pains. Without adequate relief, excess pressure can develop under areas like the shoulders and hips, causing or exacerbating tension.
The Birch Natural’s medium-firm feel allows most sleepers to sink just enough for pressure relief. In addition, because latex is naturally pressure-relieving, most sleepers should experience a pressure-free sleep experience. sleepers. However, lighter side sleepers, who won’t sink into this mattress quite as much, may prefer something softer.
Back Pain – The supportive coils and medium firmness of this bed should provide excellent relief for those who experience back pain, as the coils help maintain spine alignment which reduces pressure felt on the lower back.
Hip Pain – Hip pain is often caused by the hips sagging too far in the bed, thus receiving an inadequate amount of cushioning. Average-weight to heavyweight people should receive ample support for this area, however, lightweight sleepers may experience too much pressure build up due to the higher firmness level.
Shoulder Pain – The shoulders tend to bear a lot of weight for side sleepers. The Birch should provide adequate relief since latex excels at pressure relief, however sleepers of a lighter weight may find it worthwhile to invest in the plush topper for deeper cushioning and relief.
Support
Health-conscious folks looking for proper spinal support should be pleased with the Birch’s medium-firm feel and supportive coils and latex. Latex is a more durable material, while the individually-wrapped coils offer plenty of pushback for spine alignment.
Together, the materials should make this bed comfortable and supportive for a variety of individuals and sleeping positions.
Motion Transfer
Due to the latex and coil construction, the Birch Natural mattress may transfer a good bit of motion from its point of origin to other parts of the bed. By not isolating movement, the Birch Natural may not be a great choice for couples or other co-sleepers as they may be disturbed by their sleep mate’s movements.

Temperature Regulation / Cooling
The Birch Natural takes advantage of the naturally moisture-wicking and breathable properties of organic cotton and wool, and latex. The pocketed coils provide additional airflow so trapped heat can escape, making this eco-friendly bed an exceptionally cooling mattress.
Performance for Couples
While sexually-active couples should enjoy the bounce of this mattress, as well as its cooling abilities, the Birch won’t be a good fit for all couples. This mattress doesn’t have great motion isolation, which may wake light sleepers who are easily disturbed.

Construction: What’s Inside the Birch Natural?
The Birch Natural mattress is made with natural cotton, wool, Talalay latex, and steel coils. The cover of this 11-inch mattress is made from all-natural cotton that is highly breathable and has a tiny bit of stretch which allows the surface to cradle you.
- The first layer contains wool mixed with rayon which acts as the mattress’s natural flame retardant.
- The second layer is another layer of organic wool, which was designed to cradle your shape while wicking away moisture and excess heat.
- The third layer is made from Talalay latex. This is where the pressure relief starts, as the latex conforms to your shape to help relieve strain from tired joints while remaining temperature-neutral and responsive.
- The fourth layer is formed with individually-wrapped coils. The advantage of wrapped coils is their ability to tailor support to your body’s shape and isolate motion. Coils along the bed’s edge are reinforced to provide edge support, allowing you to sit and sleep near the edge of the bed.
- The fifth layer is made of flame-resistant wool batting. This stabilizes the coils and gives the bed a sturdy foundation all while creating a more natural fire resistance barrier.
The optional topper adds three inches of wool and latex for extra cushioning on the surface of the bed.
*Note that the company does not publish the full measurements of the bed’s layers online.

Overall Summary
The Birch Natural is an eco-friendly bed that pairs latex and individually-wrapped coils for a versatile hybrid sleep experience.

Side Sleepers
Side sleepers who stick in this position exclusively may consider the addition of a plush topper that provides more cushioning to the side of their body, which usually bears more weight across a smaller surface area in this position. However, most side sleepers should find adequate pressure relief and support with the Birch Natural.

Back Sleepers
Back sleepers are a great fit for this mattress. The best mattresses for back sleepers have a good blend of support and pressure relief, and the Birch Natural’s medium-firm feel, supportive coils, and latex comfort layer provide just that.

Stomach Sleepers
The Birch Natural should complement most stomach sleepers. This mattress has supportive steel coils to keep the midsection from dipping too much, which is important for healthy spine alignment. However, heavier stomach sleepers may want a firmer option.

Combination Sleepers
The high-bounce and quick responsiveness is good news for combination sleepers, who typically switch between different positions throughout the night. The Birch Natural’s coil and latex design is helpful for this group because this makes it easier for them to adjust and move around.

Couples
Adequate edge support and great bounce should assist couples looking to improve their collective sleep. While the medium firmness should appeal to a wide range of sleepers, adding the topper could soften the bed for side-sleeping couples. However, this bed won’t isolate motion as much, so it may not be the best for partners with different sleeping habits.

Heavy Sleepers
While this hybrid mattress was built for long-term durability and support, some heavier folks may find it too soft. Individuals who are heavier than average may want to steer towards a firmer bed that provides extra reinforcement for sleepers over 230 pounds.

Lightweight Sleepers
This medium-firm hybrid should be a good fit for stomach and back sleepers of a lighter weight, although petite side sleepers may want a softer bed for greater pressure relief. The optional plush topper could assist these sleepers in finding contouring comfort, especially when sleeping on the side.

Average Weight Sleepers
Average weight sleepers, especially those who snooze on their backs and sides, should enjoy the gentle cradling by the Talalay upper layers as well as the supportiveness of the individually-wrapped coils.
Overall Value
This environmentally-minded mattress offers sleepers a lot of value. Its combination of wool, latex, and steel coils is a versatile mix that should accommodate most sleepers, plus it comes with a 25-year warranty – substantially higher than the industry standard. Not only are these materials eco-friendly, but they’re also more durable which should make this mattress a smart investment for many.
Our Verdict
The Birch Natural is a comfortable, supportive, and eco-friendly mattress that should work for a wide array of body body types and preferred sleep positions. Its combination of pressure-relieving latex and individually-wrapped coils also promote ample breathability, making for a cooler night’s rest.
Buoyancy is the name of the game with this mattress, making it a great fit for combination sleepers, sexually-active couples, and anyone with mobility issues who needs help with repositioning. However, this bouncy quality doesn’t bode well for couples, as it may cause partners to feel their bedmate’s movements.
