A characteristic feature of a pocket mattress is its insert made of springs, each of which is located in separate pockets of non-woven interlinings or polyurethane foam. This allows independent work of every spring which ensures that the mattress insert ideally adjusts itself to the anatomical spine profile. Different types of components, such as latex, biogreen foam, HR foam, sisal, cashmere, fluffy fabric, sheep wool, as well as a cover of a wide rabge of properties can be used on both sides of each pocket insert.
