A sheet to be arranged on a mattress of a bed or the like comprises a first foil (12) of a water-permeable material and defining a circumferential outer rim and a second foil (14) of a water-impermeable material and defining a circumferential outer rim. The first and second foils (12 and 14) are joined together along a sealing (18) at the outer circumferential rims of the first and second foils, defining a sealed enclosure therebetween. The sheet (10) further comprises a body of non-water-absorbent and elastic fibers (24) which fill out the sealed enclosure and define a plurality of capillary cavities within the body when the sheet is not mechanically influenced, in which capillary cavities water may be accumulated through capillary action. The body is collapsible through elastic deformation of the elastic fibers when the sheet is exposed to a mechanical impact, such as the weight of a person resting on said sheet. The sheet further comprises two gripping strips (26, 28) provided at the outer surface of the sheet opposite to the first foil (12), which gripping strips are provided at opposite rim segments of the sealing. The sheet (10) is preferably used in connection with a mat conveyor and preferably constitutes an element of an assembly also including the mat conveyor. |
