Our Materials

Naturally Comfortable

Our materials come from nature - whether it be wool sustainably sheared from New Zealand sheep or latex tapped from trees. These premium materials are comfortable on your body and your conscience.

Organic Wool

Birch Wool plays a key role in providing comfort and insulation to your mattress. We strive to supply the best quality natural & organic wool that is sourced sustainably, which is why all the wool in our products can be traced back to its individual farm.
Organic Wool close-up texture
The Orthocortex and paracortex construction in the wool allows for the curl in the wool fibers acting as a spring to help retain shape for longer and providing durability.
The high-stretch and versatile nature of our wool allows it to be bent over 20,000 times before it breaks.
The hygroscopic nature and multi-layer cellular structure of wool create a natural insulator to regulate temperature.
When exposed to an open flame, wool fibers turns to carbon which resists fire. This makes wool one of the safest fibers for fire safety.

Organic Cashmere

Cashmere is well known across the globe as a luxuriously soft, premium material. It comes from the dense and downy undercoat of cashmere goats who live in some of the harshest climates in the world. These ultra-fine, lightweight hairs have incredible insulating and moisture wicking properties, which allow for exceptional temperature regulation. This keeps the goats warm in the winter, but also cools them down and keeps them dry in the summer.

The organic virgin cashmere we source for the Birch Luxe Natural Mattress is certified by the Global Organic Textile Standard (GOTS) and is naturally very elastic, durable, and breathable. The fine hairs come from free range goats that are tended by nomadic herders in Inner Mongolia who comb and shear the goats annually.

While cashmere has grown in popularity, it is still considered rare. In fact, it is combed and gathered from cashmere goats just once a year. 
Cashmere is very breathable and has incredible insulating and moisture wicking properties, which makes it exceptional at regulating temperature.
The virgin organic cashmere we source is certified at the highest order by the Global Organic Textile Standard (GOTS).

Natural Latex

Latex is vital in providing the cradling support of your mattress. We use 100% natural latex sustainably tapped from the tropical rubber tree Hevea Brasiliensis, which grow in Southeast Asia, Africa, and Brazil. All of the latex we use is both eco-INSTITUT Certified and GREENGUARD Gold Certified to ensure safety and low emissions. Additionally, we source exclusively from closely monitored plantations.

The Birch Natural Mattress, Luxe Natural Mattress, Plush Organic Mattress Topper, and Organic Pillow all feature Talalay latex.

Natural latex is not susceptible to molding and accumulating harsh microbes. It acts as a natural barrier to dust mites.
Talalay latex is up to 7 times more breathable than other types of latex due to its aerated pouring and manufacturing process.

Our mattresses have been tested and found to produce low to no volatile organic compounds (VOCs). 

Organic Cotton

Cotton is a highly breathable fiber used in your mattress cover. We use organic GOTS Certified cotton designed to be soft and cool to the touch with a sleek tufted design. Additionally, our cotton is a natural color and provides great moisture wicking benefits.
