Wool is the only material that both absorbs and releases moisture efficiently thereby maintaining your body temperature comfortably. Wool has the following benefits as the insulation and fill in bedding products:

• Environmentally safe
• Safe for children, pets, and seniors
• Durable
• Extremely comfortable
  
• No off-gassing
  
• Anti-microbial
• Moisture wicking
• Excellent insular properties
  

The other materials used in bedding are unable to provide you with the same benefits; polyester does not absorb sufficient moisture, neither do down or feathers. Cotton and polyurethane foam (including memory foam) absorb moisture but do not readily release it.

With these materials your body temperature is constantly shifting above and below 98.6 degrees Fahrenheit, which reduces sleep quality by causing restlessness. Reduced sleep quality can in turn lead to reduced performance of the immune system.
