A gas-inflatable, floatable, portable seat is especially adapted for supporting a child or other person in sitting position and is designed to be attached to a boat or other vehicle or be independently floatable on the water. The seat comprises a first, generally annular-shaped lower inflatable float chamber fabricated from flexible sheet material defining a lower leg compartment for a person and 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 provide armrests on opposite sides of the open segment. An inflatable seat structure comprises an upstanding back projecting upwardly of the second float chamber with a generally upstanding outer back face and a seat cushion projecting inwardly of the back into the leg compartment through the open segment of the second float chamber to support a child or person in sitting position. A bottom wall structure including relatively dense material forms a closed lower end of the leg compartment adjacent the lower level of the first float chamber and provides ballast for maintaining the seat with the back in an upstanding position when placed on the water.
