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.

Additional Coir Facts

How It's Made

Coir is harvested from coconuts, shredded, and then packed into a layer for use in bedding.

How it is Used in Bedding

Based on how tightly packed the coir is, it can be used in the surface, middle, or lower parts of a mattress. It is generally marketed as an all-natural, eco-conscious alternative to traditional mattresses types. Because of that, it is often supplemented with latex, which is also a good material for those with toxicity sensitivities.
