An air adjustable waterbed mattress which is adapted to support one or more persons on a sleeping surface. An air chamber unit is contained within a liquid-filled bladder and extends from one side of the bladder toward the other. On inflation, the air chamber unit supports a bladder-formed sleeping surface with the amount of support being determined by the amount of inflation. One or more air chamber units may be selectively positioned within the bladder and each unit is preferably formed of multiple chambers.
