Birch Mattress Review


Helix Sleep is an e-commerce sleep company established in 2015, with its headquarters in New York City. Via their online storefront, they sell sleep products across the US, including the Birch mattress through its Birch brand.

The Birch mattress is an eco-friendly mattress with a focus on organic materials. It’s a new presence on the market but packs a powerful punch, with its latex hybrid design and focus on sustainability. The mattress holds GREENGUARD Gold, Rainforest Alliance, and OEKO-TEX certifications, so it’s an obvious choice for green shoppers and those who want to avoid synthetic materials and toxic chemicals.

The Birch also stands out as a breathable mattress that maintains temperature neutrality throughout the year, which will make it popular with sleepers who sleep hot or desire more temperature control. The Birch will suit the majority of sleepers with its balance between firmness, support, and comfort.

In this review, we’re taking a closer look at the Birch, including its specifications, pros and cons, and why you may want to consider it as your next mattress purchase.

Birch Mattress Overview

Birch Mattress

An eco-friendly mattress to suit most sleepers.


The Birch is an 11-inch hybrid latex mattress, featuring layers of organic and natural materials on a base of individually-wrapped coils. It’s available in the standard range of sizes, from Twin to Cal King.

The bed is made up of six distinct layers:

  • A breathable yet robust cotton cover made from 100% organic cotton.
  • A fire-resistant layer featuring natural wool fibers with rayon. This layer uses the natural fire-resistant properties of wool in place of plastic or toxic fire-resistant chemicals.
  • A wool comfort layer that’s 100% natural and organic, designed for comfort and temperature regulation.
  • A natural latex pressure relief layer. The Talalay latex is OEKO-TEX and Rainforest Alliance certified and is designed to offer targeted pressure relief.
  • An individually-wrapped coil support layer. US-made steel coils provide dynamic pressure relief, while reinforced outer coils offer excellent edge support.
  • A 100% natural and organic wool batting base for stability.

Together, the Birch’s layers work to create a breathable and comfortable sleep experience. Air can move freely through the natural fabric layers, the foam of the latex, and between the individually-wrapped coils.

The bed’s primary support comes from the Talalay latex layer and the coils, which help to create zones of support where it’s most needed. The additional edge support helps to offset some of the weaknesses of latex beds in that area, giving you the maximum possible sleepable surface.


The Birch is available in one firmness option, which rates at a medium firm. This is one of the most popular mattress firmness levels and is suitable for a majority of sleepers. It offers an ideal compromise between comfort and support. However, the latex construction of this mattress means that at this firmness level it lacks the same conforming factor of a comparable memory foam mattress.

The Birch 3-inch plush pillow top is sold as an optional extra and may work well for sleepers who are on the fence about buying the Birch at this firmness level.


The bed’s price varies by the mattress dimensions and the price for each size is shown in the following table. Note that this cost will be higher if you’re adding optional extras, such as the pillow top or 10-year accidental damage cover.

Overall, the Birch comes it at a lower price point than many latex hybrid mattresses, despite its focus on natural and organic materials. That makes it a good choice for shoppers on a budget. Prices are listed before any discounts or sales.

Birch Mattress Breakdown

To help you establish whether the Birch should be your mattress of choice, we’ve answered a few common questions. To learn more about our mattress review process, check out our methodology.

Is it made from quality materials?

While Helix Sleep is a new name on the mattress market, the Birch is made primarily with 100% organic and natural materials. The mattress features natural cotton, wool, and Talalay latex, all made without harmful additives and the mattress has achieved GREENGUARD Gold certification.

Like many of its online competitors, there’s little long-term performance data due to Helix’s relatively short operational period, but natural materials are typically durable, so you can expect the Birch to last its expected lifespan with proper care.

How long will it last?

The Birch should last at least eight years and will likely outlive similar hybrid latex mattresses thanks to the natural materials in its construction. However, Birch is a new brand and the Birch mattress doesn’t have a lot of performance data yet.

There’s no need to rotate the Birch mattress to maximize its longevity, though sleepers can rotate (but not flip) the mattress if they prefer.

How well does it conform to my body?

As a medium-firm latex mattress, support and comfort are higher on the Birch’s list of priorities than conforming.

Sleepers who will be happy with a compromise can opt for the extra pillow top layer, which can add some additional conforming. However, the bed won’t be able to compare to a similar memory foam bed in this arena.

Is the edge supportive?

Latex beds often suffer from a lack of edge support, as the latex deforms as easily at the edge as it does in the center. This can reduce the sleepable area.

The Birch doesn’t dodge this problem entirely, but reinforced coils along the outer edge of the bed do help to offset it. This gives the Birch better edge support than similar latex and latex hybrid mattresses.

Does it sleep hot?

The Birch mattress is great for sleepers who prioritize temperature control in their mattress. The cotton and wool layers are exceptionally breathable and, as natural materials, they maintain a comfortable temperature year-round.

The Talalay latex and individually-wrapped coils also allow for consistent airflow, so temperature neutrality is one of the stand-out features of the Birch.

Will it off-gas when it’s delivered?

Many mattresses can emit odors when new. In extreme cases, these odors can be unpleasant and linger for a long time.

While even natural materials can off-gas to some degree, the kind of off-gassing sleepers want to know about is the kind usually associated with harsh chemicals and synthetic materials. As the Birch is made from primarily natural and organic materials, off-gassing is nearly absent and any smells will disappear quickly.

Will I feel my partner move during the night?

As a hybrid mattress, you can expect a slight, but detectable amount of motion transfer from the Birch. Coils typically transfer motion, as most people know from sleeping on an innerspring mattress. However, the Talalay latex layer does help to offset this problem. While this does create a reasonable compromise, sleepers who place a high priority on motion isolation may want to think twice about the Birch. This will be particularly important for couples where one or both partners are light sleepers.

Who is Best Suited for a Birch Mattress?

As a medium firm hybrid latex mattress, the Birch suits a wide range of sleepers. Back, side, and front sleepers will all find the Birch offers a reasonable level of comfort. Exceptionally light individuals may find it slightly too firm, but most sleepers will find it sleeps well. For sleepers who find the Birch too firm, the optional plush pillow topper can add a little more comfort.

The Birch may not be as suitable for sleepers who like a lot of conforming in their mattress. The medium firmness and latex construction lean more toward comfort and support than conforming.

Of course, the Birch will also appeal to sleepers looking for an eco-friendly mattress made with sustainable manufacturing techniques. With its 100% organic and natural cotton, wool, and latex, the Birch is very green, and its US-made steel coils are made with sustainable techniques.

Sleepers who want to avoid synthetic materials and toxic chemicals may choose the Birch for many of the same reasons, as there are fewer man-made components in the Birch.

Besides its eco-friendliness, the Birch also offers excellent breathability and temperature neutrality. Sleepers who struggle to maintain a comfortable temperature throughout the night will benefit from the Birch’s comfortable yet breathable materials.

For shoppers on a budget, the Birch is a little cheaper than some of its immediate competitors, which is surprising in a mattress that uses so many organic and natural materials.

Overall, the Birch is something of a jack-of-all-trades. It’ll suit the average sleeper well, so only sleepers who know they have particular needs may find it lacking. Couples may need to be a little more cautious, as motion transfer is one of the bed’s main potential weaknesses thanks to its hybrid design.

Ready to Buy a Birch Mattress?

Before you make your final decision, let’s take a look at a few other key details you need to know about the Birch mattress: its sleep trial, warranty, and shipping and delivery details.

Sleep Trial

The Birch comes with a 100-night sleep trial with a mandatory 30-day break-in period. At any time during this trial, you can return the mattress for a full refund. This break-in period ensures you experience the mattress in its usual state, as a fresh mattress will be slightly firmer and more resistant than an older one.


The Birch comes with a 25-year limited warranty, subject to proper usage per the manufacturer’s instructions. This is broken down into a 1-10 year period at full coverage and an 11-25 year period prorated limited coverage.

For years 1-10, the mattress is warranted against manufacturing defects and Birch will repair or replace the mattress at no additional cost.

From years 11-25, Birch may replace the mattress at a prorated charge including transportation and shipping charges. This begins at 50% of the original purchase price in the 11th year, increasing by 5% for each year thereafter.

Availability and Delivery

The Birch mattress is sold exclusively through the Birch website, though Helix Sleep does maintain a showroom in New York City where sleepers can experience the Birch.

Shipping is free and delivery is available to all US states. Orders are typically fulfilled within 4-8 business days.
