Abstract: An air mattress with at least one cavity to be filled with air, which is bounded by a sitting and reclining surface, a bottom surface disposed opposite the sitting and reclining surface, and a peripheral side surface connecting the sitting and reclining surface and the bottom surface. Magnets, each incorporated in separate chambers, are arranged on the side surface on the sitting or reclining surface and on the bottom surface for the connection of air mattresses of the same design.

Abstract: An identification document has a substrate and a laminating film bonded to the substrate. The surface of the substrate facing the laminating film bears first text, numeric and/or image data detectable with the naked eye at least when illuminated by daylight and a first zone with a fluorescent substance. Under excitation with light in a specific wavelength range the substance fluoresces in colour in a manner detectable with the naked eye. The laminating film has a second zone which bears second text, numeric and/or image data. The first zone of the surface of the substrate and the second zone of the laminating film overlap one another at least partially.
