PCT No. PCT/SE88/00401 Sec. 371 Date Jun. 14, 1989 Sec. 102(e) Date Jun. 14, 1989 PCT Filed Aug. 9, 1988 PCT Pub. No. WO89/01306 PCT Pub. Date Feb. 23, 1989.A body-supporting device forming the seat (1) and/or the backrest (15) of a chair and adapted to avoid sweating caused by the thermal insulation of the chair includes at least those sections (2) of the exterior surface of the device that form the support surfaces for parts of the body of a person sitting in the chair made of air-permeable material, an internal bag member (6) having air opening (11) to the exterior of the device arranged to communicate with the interior side of the air-permeable sections (2) through holes (7) and a suction device capable of producing a negative air pressure connected to the opening. The interior of the body-supporting device is arranged so that when the suction device is running, air exterior to the support surfaces is drawn through the air-permeable sections, (2, 5), and via interior porous layer (8) and porous body (9) within the bag of the body-supporting device and out of it through the opening (11) to remove heat radiated by the body of the person, in particular from the region between contacting parts of the body and the air-permeable sections, and to cool those parts of the body by the airstreams thus created.
