Temperature
Have you ever slept with someone and couldn’t seem to agree on how many covers to have on the bed during the night, or even flipped the covers off because you were too hot? These are problems that are common with those who do not use wool in their sleep environment. Wool is the only fiber that will automatically adjust to your skins temperature while allowing your partners side to adjust to their skin
Longevity
Wool is an extremely durable fiber. In fact the oldest carpet in the world, which dates back to the fifth century B.C. was made from wool. Wool can be bent over 20,000 times without breaking. Silk will break after 1,800 bends and rayon after only 75. Wools natural resilience is why clothes made of wool are wrinkle resistant when dry.
Flame resistance
For safety, wool is very good for bedding because it is naturally flame resistant due to its moisture content plus the protein keratin. Wool requires a higher temperature to ignite than other natural fibers. When aflame, wool burns slowly, smoldering and charring but giving off little heat. Other fibers ignite and burn readily even after the flame is taken away. In the event of a fire, man made fibers like polyester and acrylics actually melt and stick to skin.
