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.
High resilience is a polyurethane foam that has a much higher responsiveness than memory foam, which has a slower response. Because of this, those that enjoy more of a bounce in their mattress will gravitate towards this type of foam.
High resilience foams are much less popular than memory foam, but they make up important layers of many popular mattresses. Oftentimes the transitional layer or base layer of memory foam mattresses will contain high resilience foam at high densities. This provides a more even feel across the mattress, and less of a sinking feeling that memory foam alone would have.
Like all polyurethane foam, high resilience foam is made of a blend of polyurethane and has a tendency to off-gas. If you are susceptible to lung issues, please do additional research on the quality of foams before purchasing.
Pros: Quicker response than memory foam provides many mattresses with an even supportive feel.
Cons: Sagging and off-gassing problems with lower quality foams.
