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.

Abstract: A bivouac shelter for residing outdoors, including a basis unit that forms a tunnel-like or sack-like body receiving space with an access opening for a person. The bivouac shelter includes a closure unit, by way of which the body receiving space is closable in a thermally insulating and airtight manner. The closure unit moreover includes a connection body that can be assembled transversely over the access opening and that is connectable to the basis unit in a thermally insulating manner. The closure unit moreover includes a hood attached onto the connection body for receipt of a head of a person lying with the body in the body receiving space. The basis unit can also include a foot-side terminating element.
