A system for securement of a baby within a bathtub. The system includes a seat attached to a frame. The seat includes a backrest, a base, and a harness, such that the harness can removably secure the baby within the backrest and the base of the seat. The frame includes a unitary rod that extends through a perimeter of the seat, and a pair of adjustable hook members. Each adjustable hook member can be widened or narrowed to snugly fit to a sidewall of the bathtub and be secured thereto by friction fit. Upon securement of the adjustable hook members to the sidewall of the bathtub and placement of the baby within the seat, the baby is safely secured to an interior of the sidewall for bathing or recreation.
