Birch, a subsidiary of Helix Sleep, is an online "bed-in-a-box" mattress brand that has been in business since 2019. The company is best known for products containing organic, natural, and sustainably sourced components. In this review, we'll take an in-depth look at the brand's flagship bed, known simply as the Birch Mattress.
Standing 11 inches thick, the Birch Mattress is considered a latex hybrid. It begins with a top layer of organic and natural wool batting, which is quite breathable and has moisture-wicking properties. The mattress also contains a layer of natural Talalay latex over a pocketed coil support core and wool batting base layer. The bed's cover is composed of organic cotton. In terms of firmness, the Birch Mattress is considered medium firm, or a 6 on the 1-10 firmness scale. This model is currently Birch's only mattress.
Does the Birch Mattress sound like a good option for you? We’ll break down everything you need to know about the bed in terms of prices and sizing options, construction and material composition, and performance ratings based on owner experiences and our own product testing.

How Much Is the Birch Mattress?
The Birch Mattress has a price-point that is slightly lower than that of the average hybrid mattress. Birch does not offer any customizations for this mattress that affect pricing, though you can bundle your mattress purchase with a Birch mattress topper, pillow, and/or bed frame. The price of these add-ons depends on which mattress size you select.
The mattress comes with a 25-year warranty that covers certain defects, such as deep surface impressions and physical flaws with the bed's design. For an additional fee, you can purchase 10-year accidental damage coverage. This protection plan covers issues that aren't considered warrantable defects, such as pet damage or stains. The accidental damage coverage costs $79 to $139, depending on the mattress size. Ground shipping is free to all 50 states, so you don't need to plan for any delivery charges. Returns are also free during the 100-night sleep trial.

How Does the Birch Mattress Feel?
The Birch Mattress offers a traditional latex hybrid feel. The latex provides a gentle, moderate body contour and responds quickly to the body, creating a noticeable bounce on the surface. This feel differs from that of a memory foam hybrid, which will respond more slowly and conform closely to the body. Many liken the feel of a latex hybrid to sleeping "on" – not "in" – the mattress. Your body shouldn't sink too much, regardless of how much you weigh.
The mattress also feels very cool and breathable thanks in part to the wool batting layer and organic cotton cover. The surface won't trap much body heat and should maintain a comfortable temperature. The ventilated latex and pocketed coil layers also promote extra air circulation. All in all, this mattress is ideal for hot sleepers, especially if they feel too warm on foam layers.
What Is the Birch Made Of?
The Birch Mattress cover is derived from organic cotton. The fabric has received certification from the Global Organic Textile Standard (GOTS), one of the world's leading authorities on organic materials.
The cover is lined with a blend of natural wool and rayon. This material is not only breathable but also flame-resistant, and serves as the bed's fire barrier.
The Birch Mattress has a top layer of organic and natural wool batting. While the wool feels soft and provides cushioning for the surface, it does not conform to the body like foam or latex. This creates plushness without sinkage, which can particularly benefit people who weigh more than 230 pounds.
The second layer consists of 2 inches of natural Talalay latex. Compared to Dunlop latex (the other common type found in mattresses), Talalay tends to feel softer and less dense, making it ideal for people who want more conforming from a latex mattress. The layer is ventilated with small holes to create added airflow near the surface. The latex has earned certifications from eco-INSTITUT and the Rainforest Alliance.
The Birch Mattress has a support core of individually pocketed coils, which are found in the majority of today's hybrid models. Pocketed coils tend to be quieter than other coil types. They also offer decent support without feeling too stiff. A base layer of natural and organic wool batting reinforces the coils.
Altogether, the Birch Mattress measures 11 inches thick and is considered a medium-profile model.
Does it Isolate Motion?
The Birch Mattress has a latex layer that responds quickly to the body, and the springs also create noticeable springiness. This may generate motion transfer that travels across the surface whenever you change sleep positions or get in and out of bed, which in turn can disturb your partner's sleep. That said, the mattress is not as bouncy as a traditional innerspring and neither you nor your partner should feel excessive transfer.
Most latex hybrids offer middle-of-the-road motion isolation. All-foam mattresses tend to outperform other mattress types in this category, especially those with at least one memory foam comfort layer. Memory foam responds slowly to the body, allowing the material to absorb movement and practically eliminate transfer. If you and/or your partner are highly sensitive to movement in bed, then you may want to consider a foam mattress. However, the Birch Mattress should be suitable if neither of you awaken easily due to motion.
Does it Sleep Cool?
Temperature control is one of this bed's main strengths. The top wool batting layer is very breathable and will not trap heat like foam. Wool also has natural moisture-wicking properties to help keep you cool during the night. Meanwhile, the ventilated latex and pocketed coil layers generate steady air currents to regulate the mattress core's temperature.
Latex typically offers better temperature neutrality than foam, which can trap a fair amount of body heat. Since they also include a coil layer for extra airflow, latex hybrids are among the coolest mattress types on average. The Birch Mattress gets an additional leg up thanks to its firm feel to keep your body level with the surface. If a mattress sinks too much, your airflow will be more restricted and overheating is more likely.
Will It Sag Along the Edges?
All mattresses sag at least a little when you sit along the edges, but hybrids like the Birch Mattress are equipped with thick, sturdy coil systems that provide bounce-back and prevent excessive sinkage. This makes getting on and off the Birch Mattress rather easy – regardless of how much you weigh – and most people should feel secure sleeping near the edges of the bed without feelings of "roll-off."
Over time, you may notice more sinkage along the perimeter. This is to be expected as the coils and other components begin to wear out. You can help preserve the edges by rotating the mattress head-to-foot every three to six months.
Is It Good for Sex?
For couples who prefer springier mattresses, the Birch Mattress will be well-suited for sex. The responsive feel allows you and your partner to move across the bed without sinking too deeply, but the latex provides decent traction that enables you to maintain a fixed position for longer periods of time. Strong perimeter reinforcement allows you to use the entire surface and breathable components should keep you from overheating.
One thing to note is noise potential. The coils should be relatively quiet at first, but over time they may produce more squeaks and creaks. As a result, the mattress may not be discreet enough for sex as it nears the end of its lifespan.
What About Off-gassing?
All new mattresses emit an off-gassing odor when you unbox them. Beds with foam layers can be particularly smelly because foam releases volatile organic compounds (VOCs), which have a strong chemical odor. The latex found in models like the Birch Mattress does not produce VOCs but some owners liken the "new latex smell" to rubber. The wool batting may also carry an odor during the first few days. However, the Birch Mattress is breathable enough to flush out bothersome smells rather quickly. We expect any odor to dissipate in a matter of days. If not, try placing the mattress in a well-ventilated room for another day or two.
What Type of Sleeper Is the Birch Mattress Best for?
The Birch Mattress offers a gentle body contour and a responsive, springy surface. This makes the mattress best suited to certain sleep positions, and less so for others.
After testing the mattress and reviewing owner experiences, we've found the mattress is a good match for back sleepers – especially those who weigh 230 pounds or less. The latex and coil layers, along with its medium firm feel, ensure even support from head to toe with minimal sagging around the shoulders, lower back, or hips.
Side sleepers are a bit different from those who sleep in the back and stomach positions. When you sleep on your side, extra cushioning is needed around the shoulders and hips to align the spine and alleviate pressure points. The Birch Mattress does not conform very closely, so side sleepers with certain body types may not receive enough padding to feel completely comfortable.
Side Sleepers: Side sleepers who weigh between 130 and 230 pounds note excellent support from the Birch Mattress. Those who weigh less than 130 pounds may find the mattress a little too firm, whereas side sleepers weighing more than 230 pounds might sink a bit too much, especially around the hips.
Combination Sleepers: Since the Birch Mattress conforms very little and feels very supportive, it is best suited to combo sleepers who rotate between the back and stomach positions. Those who sometimes sleep on their sides may also find the mattress comfortable, depending on how much they weigh.
Back Sleepers: Back sleepers who weigh up to 230 pounds should feel adequately supported on the Birch Mattress. Those who weigh more may experience some sinkage between the shoulders and waist, but probably not to an excessive degree.
Stomach Sleepers: Stomach sleepers weighing less than 130 pounds should also receive adequate support from the Birch Mattress and feel less pressure in the neck, shoulders, lower back, and hips. Like back sleepers, stomach sleepers typically need mattresses that reinforce the body and prevent excessive sinkage. Those who weigh 130 pounds or more should also find the mattress comfortable, but the potential for sagging and added pressure is a bit higher.
How Does Body Weight Impact the Birch Mattress' Performance?
After testing the Birch Mattress, we've found this model is often best suited to people who weigh between 130 and 230 pounds. The bed has a medium firm feel that offers a balance of cushioning and support. Sleepers in this weight range should experience some body conforming from the latex layer without sinking too much beneath the midsection, waist, and other areas where they carry a larger amount of weight.
Some sleepers who weigh more than 230 pounds may also feel comfortable on the Birch Mattress, though some may find it does not provide enough firmness or support. This can lead to certain issues such as excessive sinkage, added aches and pains, and difficulty getting on and off the mattress. A firm or extra firm mattress will be more suitable for these individuals.
For some people who weigh less than 130 pounds – particularly side sleepers – the mattress may feel too firm instead. A softer mattress topper can adjust the bed's surface feel to some extent, but insufficient conforming can negatively affect spinal alignment and cause added pressure points to occur. These sleepers may want to consider a softer mattress instead.
Is it Good for Couples?
The Birch Mattress offers some benefits for couples, as well as a few drawbacks. One major advantage of the mattress is strong edge support. By reinforcing the perimeter with strong pocketed coils, the mattress allows you and your partner to rest comfortably across the entire surface. Mattresses with weaker support feel less stable around the edges and often confine co-sleepers to the middle of the bed. Consistent temperature neutrality is another strong point. The mattress has breathable components that won't trap too much body heat or make you feel excessively warm. Strong responsiveness can be a plus if you and your partner prefer a bouncier bed for sex, too.
The mattress isolates movement somewhat, but you should still expect a noticeable amount of motion transfer when your partner moves around or gets in and out of bed (and vice versa). This may cause sleep disturbances, depending on how sensitive you are to movement in bed. The coils may become louder over time, as well, increasing the potential for noise-related disruptions.
Birch's Trial, Warranty, and Shipping Policies

Birch will issue full product refunds on all returns and arrange for couriers to pick up the mattress from your residence. All returned mattresses are either donated to charity or recycled.
|Warranty||The Birch Mattress comes with a 25-year warranty, which is partially prorated. During the first 10 years of ownership, Birch agrees to cover all shipping fees and repair or replacement costs if your mattress develops a defect. This is known as the non-prorated phase of the warranty.
Starting in year 11, you'll pay 50 percent of the original mattress price if your bed becomes defective and needs to be replaced. This percentage increases by 5 percent increments until year 20, at which time you'll pay 95 percent of the original sticker price until the warranty expires.
Defects covered under this warranty include sagging or body impressions in the surface that measure 1 inch or deeper, and physical flaws that cause mattress components to deteriorate prematurely. Other issues are not covered under this warranty. Birch's 10-year accidental damage protection plan covers additional problems, including stains and liquid damage, burns, rips and tears, and pet damage. This plan costs $79 to $139, depending on the mattress size.
