Materials We Prefer

Wool: Wool is a renewable fiber that does not cause harm to the animal to harvest the wool. Wool is an extremely diverse fiber and naturally contains nitrogen and moisture, which gives the fiber low inflammability. Wool has balanced thermal insulation properties - meaning it is warm in winter and cool in the summer.  Wool is hypoallergenic - it is resistant to bacteria, mold and mildew that can trigger allergic reactions in many people. It absorbs harmful pollutants - not only does wool absorb many harmful pollutants from the air, but it also does not re-emit them. It's estimated that wool used in interiors can help purify the air for 30 years. (1)

Plastics: The only plastic you will find in the store are those products that are made from recycled plastics in order to reduce the waste stream. It is estimated that eight million tons of plastic are released into the oceans every year. Marine animals eat the plastic which compromises their health and spreads these toxic chemicals throughout the food chain. The chemicals in plastics have been linked to serious health conditions in humans, including birth defects, infertility, cognitive decline and cancer.
Recent research suggests that humans consume about five grams of small plastic particles every week, which is about the weight of your credit card.
"The plastic particles make their way into the human food chain from packaging waste, entering the body through sea salt, seafood and even drinking water, scientists at the Medical University of Vienna explained.
The nanoplastics — which are less than 0.001 millimeters in size — and microplastics — which span 0.0001 to 5 millimeters — have the ability to change the gut microbiome composition, according to the study published in the journal Exposure & Health". (2)
