Abstract: A bathtub lift device for assisting an individual, especially an elderly, handicapped or convalescing individual, in getting into and out of a bathtub includes a rectangular-shaped inflatable and deflatable cushion comprised of interconnected sections that deploy in accordion-like manner, with the cushion disposed within the bathtub and having an underside that includes suction cups to secure the device to the bathtub floor and an upper side that includes a non-slip surface for safety whereupon inflation of the cushion by an electrical air pump connected to the cushion by an air line, and which also includes an air flow control and release valve, causes the sections to expand in accordion-like manner thereby elevating the cushion to a height adjacent to the bathtub sidewalls and deflation of the cushion causes the sections to collapse in an accordion-like manner thereby lowering the cushion, and the individual seated thereon, within the bathtub.
