Man-made materials used as fillers for pillows have their drawbacks both from both an environmental and health standpoint. They certainly are not ideal for resting one’s head on these materials for 7-8 hours per day.
Polyester fiberfill is petroleum-based, using a nonrenewable resource that is very energy intensive to make. Also, the main toxic chemical in polyester is ethylene glycol, which is absorbed by the human body by inhalation and through the skin. This chemical is known to damage kidneys and the central nervous system. Foam pillows such as mypillows.com, and memory foam pillows contain polyurethane that can release VOCs (volatile organic compounds) such as formaldehyde and benzene. These chemicals are known to be carcinogenic to humans. While these chemicals might not emit high enough concentrations to trigger an adverse reaction in most people, why take the chance? It certainly is discomforting to think about what your body is ingesting or absorbing while trying to get your beauty sleep.
Fortunately, there are all natural buckwheat hulls used to fill pillows. This environmentally friendly material is free of pesticides and fertilizers. They have grown in popularity with the evolution of the Green Movement. Because they are plant material, those supporting the Animal Rights Movement favor buckwheat hulls, too. This all-natural plant material also has been a mainstay in the Asian sleep industry for a thousand years.
Buckwheat is a crop plant that is grown colder climates in Asia and North America. In the US, they are grown in North Dakota, Maine, and Northern New York where the growing season is short.

The hulls used in this manner are valued for their durability and therapeutic uses.
