— natural coconut fiber combined with a polymer filler, usually latex (see the relevant paragraph). The key feature of coir is high rigidity, so the use of this material is usually a sign of a hard mattress (or a product where at least one of the sides is hard). The disadvantages of coir are a rather high cost and a tendency to crumble under a significant load.
