What Are Those Materials, Anyway?


At Birch, we know how much our materials matter. That’s why we’re dedicated to creating high-quality products that are both natural and organic.


That’s also why we’re committed to being transparent about what exactly those materials are every step of the way.


The Birch Natural Mattress and Birch Luxe Natural Mattress both combine organic cotton, natural latex, and organic wool to create a high quality, comfortable mattress with the right amount of support, comfort, and durability you've come to expect from Birch. It’s easy to point to our certifications as proof enough that we’re committed to the highest standard possible, but we're happy to go a step further so you understand why we've chosen these all natural materials to go into our mattresses.


Here’s a closer look at the materials we use across our Birch products and why we choose to ensure that each and every one of them adheres to the very highest safety and quality standards.

Organic Wool
Our wool selection is key to the comfort you feel from every Birch product and we are proud to rely on sustainable sourcing strategies for this material. Supplied by individual farms across New Zealand and manufactured right here in the United States, our wool is sustainably sourced and produced.
Natural Latex
The natural latex used in each Birch Natural Mattress and Birch Luxe Natural Mattress is key to providing the support and pressure relief that you need for a great night’s sleep. We source our rubber directly from rubber trees across Southeast Asia and South America and then it is is carefully made into latex foam to ensure consistency across every inch of your mattress.

The Birch Natural Mattress features Talalay latex, while the Birch Luxe Natural Mattress upgrades to Pulse latex.

All of our latex is eco-INSTITUT certifed to ensure the utmost safety for you and your loved ones.

Organic Cotton
Multiple parts of the Birch mattresses feature organic GOTS Certified and Fair Trade cotton because it’s a naturally breathable, hypoallergenic fiber that promotes airflow, and is both soft and cool to the touch.

Organic Cashmere
Cashmere is very breathable premium material and has incredible insulating and moisture wicking properties, making it exceptional at regulating temperature. The organic virgin cashmere we source for the Birch Luxe Natural Mattress is certified by the Global Organic Textile Standard (GOTS) and these fine hairs come from free range goats that are tended by nomadic herders in Inner Mongolia who comb and shear the goats annually.
Birch Adhesives
Without the right adhesives, your Birch mattress could see shifting across the comfort and pressure relief layers during both the compression and shipping processes. To keep each layer of your mattress secure, we rely on a minimal amount of water-based adhesive between the comfort layers and support coils. Our adhesive does not have any off-gassing properties and has been approved as an accessory for use in GOTS certified products.
FR Layer

The fire retardant layer in your mattress is essential to keeping you safe in the event of an emergency but common FR layers often rely on plastics or fiberglass materials to provide protection. 


Instead, the Birch mattresses use 100% organic wool fibers to provide the protection you need without exposure to dangerous fire retardants.


The ¼ inch FR layer in all of our Birch mattresses is placed directly below the mattress cover to ensure your safety, and is also built into the bottom layer to provide protection throughout the Birch Natural Mattress and Birch Luxe Natural Mattress.
