Wool is made of sheep fur. It is sheared from the sheep multiple times in their lives.
The most famous kind of wool being used in mattresses is New Zealand wool because of its attention to quality.
Wool is commonly found in the cover or as a comfort layer. As a comfort layer, it is packed tightly in the mattress so it can add softness to the top layers of the mattress. Some untreated wool may have a slight natural barnyard smell. It is also a natural fire retardent.
Pros: Wool is an all natural alternative to other types of comfort layers.
Cons: The quality of wool bedding is entirely dependent on mattress craftmanship. If the packing is too loose, there can be quick sagging and durability issues.
