Abstract: An apparatus and method for supporting a pregnant user is disclosed comprising, in combination, a fixed support portion having a fixed configuration for supporting a portion of the user, and a variable support portion coupled to the fixed support portion and having a plurality of configurations for supporting a different abdominal portion of the user with each configuration of the plurality of configurations. The fixed support portion comprises a plurality of inter-connected, inflatable, tubular members. The variable support portion comprises a plurality of independent, concentric, inflatable, annular members attached to an independent, inflatable, cylindrical member. The variable support portion is in proximity to the abdomen of a user lying thereon, and the cylindrical member and the annular members are selectively inflated to conform comfortably to a protruding abdomen of a pregnant user. This support apparatus is especially useful as an air mattress and a floatation raft.
