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

Our wool plays a key role in providing comfort and insulation to your mattress. We strive to supply high quality natural & organic wool, which is why all the wool in our products can be traced back to its individual farms that practice sustainable shearing.

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.

Natural Latex

Latex is vital in providing the cradling support of your mattress. We use natural latex sustainably tapped from the tropical rubber tree Hevea Brasiliensis, soured from Sri Lanka. 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 natural latex.

Natural latex is not susceptible to molding and accumulating harsh microbes. It acts as a natural barrier to dust mites.

Our natural latex is designed for optimal airflow through the body of your mattress, keeping you cool while you sleep.

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.
