ABSTRACT:
Chair or armchair, its seat (1) and back (2) being provided with a covering (3, 6; 7, 10) of a resilient material such as foam rubber or a similar material. Both the seat (1) and the back (2) contain a cushion (5, 9) filled with water or a similar material, with a thickness between 20 and 80 mm when in filled condition. The internal spaces of the cushions (5, 9) are connected to each other. The cushions form an integral unity (11) and at the point where the cushion (5) for the seat (1) connects to the cushion (9) for the back (2), a partition has been mounted, which is obtained in that the integral cushion (11) is provided with an elongated slot (12) extending in transverse direction, or in that it is pressed by one or more rollers (15, 16).
