A water bed having inner communicable air chambers is provided. The water bed has a mattress body formed of an upper and a lower sheet with an air inlet, a water inlet, and an air vent provided thereon. A plurality of mutually communicable long air chambers arranged in parallel are sealed inside the mattress body by means of radioheating to longitudinally divide an inner space of the mattress body into a plurality of alternate air and water passages. The air chambers each have an oval-shaped cross-sectional contour that permits the air chambers to change their shape in accordance with the amount of air filled therein. The mattress body is thereby maintained in a soft, elastic, stable condition. The air chambers reduce the amount of water required to fill the mattress body and thereby reduce the weight of the mattress body and shorten the time required to heat or cool the water bed.
