An arrangement in a water mattress (1) for a water bed, the water mattress (1) comprising a water bag (2) made from a flexible and water tight sheet material, which is provided in a frame (3) of a resilient material, intended to be supported, in use, by a firm surface, and where bottom (4) and top (5) of water bag (2) are mutually connected alongside the upper narrow edge (3a) of said resilient frame, the top of water bag (2) being secured to the frame (3). The bottom (4) of water bag (2) is in contact with inner inclined lateral surfaces (3b) of frame (3) and the supporting surface. Bottom (4) of water bag (2) is double with an intermediate air chamber (8) connected with a hose (9) for air supply. In top surface (8a) of air chamber (8) upwards projecting flexible air pockets (10) are provided which open towards air chamber (8). When air is supplied to air chamber (8) and air pockets (10), the air pockets will displace water in water bag (2), so that a person lying on the supporting surface of the water mattress will be supported by water and air in said air pockets (10). |
