A gas-inflatable, floating, portable, seat is especially adapted for supporting a child or other person in sitting position and is designed to be used in a boat or other vehicle or independently float on the water. The seat includes a first, generally annular-shaped, lower, inflatable float chamber fabricated from flexible sheet material adapted to provide needed buoyancy when placed in the water. A second, generally annular-shaped, upper, inflatable float chamber is secured on top of the first chamber and is formed with an open segment on a backside thereof to accommodate an upright seat back and the second chamber provides armrests on opposite sides of the seat back. A separately inflatable, seat cushion is detachably mounted on the lower float chamber in the open segment of the second float chamber. The seat includes a separately inflatable generally upstanding seat back projecting upwardly of the armrests and joined at the lower end to a portion of the lower float chamber between the ends of the upper float chamber. A bottom wall is provided to close off the space adjacent the lower level of the first float chamber and a second wall is provided to close off the space at an upper level of the lower float chamber to provide a ballast chamber to hold water as desired for maintaining the seat back in an upstanding position when the seat is floating on the water.
