  • Covers of comfort mattresses for example, consist of a solid fabric or of three-dimensional, elastic materials such as terry or multi-layered jersey. Mattresses are often constructed divided into several lying zones, which can be adapted to the different needs of the individual body regions on support. On the mattress cover high demands are made from a mechanical and hygienic point of view. Often, the mattress cover is removable so that it can be washed or cleaned, yet durable antimicrobial equipment should be provided.
  • Mattresses are often made in one piece for cost reasons. By using lightweight materials for the various components, weight-reduced mattresses can be made to make turning, venting and pating easier. In part, mattresses also have different surfaces with different equipment, eg. B. a summer and a winter side. Grab handles on the sides of the mattress allow for handling larger mattresses.
  • the multi-layer materials and components of a mattress must be firmly joined together (slip resistance), so that they do not delaminate or slip when used as intended, on the one hand, and on the other hand also provide a sufficiently good ease of use. Further, since mattresses have direct contact with the wearer's body during daily use, the antimicrobial finish of the mattress, and especially the mattress wedge, is of great importance.
