Coconut coir is a plate out of fibre of brown «jacket» of coconut bonded by spattering of latex solutions. In furniture production coir is used as the basis for core and hard wadding. Main features of this ecologically clean natural material are: its microbicidal properties, it is not putrefiable and it does not provoke allergic reactions. Density of coir plates - 80-90 kg/m3. The structure impregnated with latex provides semi-stiff, springing core - the most important element of the mattress durability. The higher the density- the stiffer the mattress.
