Coir or coconut fiber is fiber from the husk of coconuts. Among other uses, it is used as a natural bedding material.
Generally, coir is used in the middle and upper layers of mattresses to provide support or responsive softness by adding more or less density of material.
Those that are allergic or sensitive to foam, may find that this all-natural, non-toxic material is a good addition. It is important to note that coir mattresses may also have additives: such as cotton, wool, or foam so it is important to do your research to make sure those materials are safe.
Pros: Eco-Friendly, non-toxic, and all natural bedding.
Cons: Comfort is dependent on the craftmanship and quality of the coir material. Low quality bedding can be quite uncomfortable.
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.
