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.
Visco elastic foam is another term for memory foam. It is a blend of polyurethane foam that was developed for airplane cushions by a NASA contract in the 1970s.
The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance. Its soft surface allows for contouring and its slow response lowers bounce.
Visco elastic foam, like all polyurethane foam, is made from a blend of substances and has a tendency to off-gas. Those with lung sensitivities should do additional research about the quality of foam to ensure that it won't aggravate them.
Pros: Contouring comfort, competitive pricepoints, and widespread options.
Cons: Sagging and off-gassing problems with lower quality foams.
