Abstract: A sleeping system for use outdoors or in non-heated indoor spaces and includes a support structure and a sleeping unit, which is arranged underneath the support structure when in use and forms an access opening for at least one person. When in use, the sleeping unit is tensioned by a tensioning device having a tensioning unit directly or indirectly via the support structure such that the sleeping unit forms a body-accommodating space that is kept in shape by the tensioning device.

Abstract: A thermally insulating single or multipart multilayer covering jacket for covering a person, includes a body side and an outer side. The covering jacket contains a transfer layer, a blocking layer, and a storage layer arranged between the transfer layer and the blocking layer. The transfer layer is arranged so as to face the body side and is water-permeable in the direction of the storage layer and water-impermeable in the direction away from the storage layer. The blocking layer is arranged so as to face the outer side and is water-impermeable in the direction away from the storage layer, and the blocking layer forms an intermediate space for storing condensed water which is formed from the steam transferred into the storage layer through the transfer layer.

Abstract: A lying system including at least one leveling chamber that can be filled with air. The lying system contains a lying side, which forms a lying surface, and a support side. The at least one leveling chamber that can be filled with air is part of a leveling device or forms part of a leveling device and can be filled with air in such a way that the lying system has locally different heights outside of the usage position. Thus, the support side can be at least partially adapted to the inclination and/or the unevenness of the ground, such that the lying surface is more even and/or less inclined than the ground in the usage position.
