Abstract
The inventive cushions (5) for sitting, leaning or lying upon are essentially constructed of a pneumatic structure and of a covering that surrounds the pneumatic structure. The pneumatic structure consists of an enclosure (2) and webs (3) resulting in the formation of chambers (4). The pneumatic structure is pressurized whereby tensioning the covering so that the ribbed surface of the pneumatic structure can no longer be clearly perceived. In other embodiments, the cushions (5) are equipped with means for individual adaptation. They can also be supplemented with reinforcing and stiffening structures. Cushions (5) can be deformed or moved relative to one another by means of pneumatic actuators.
