Baby bath seats and rings are devices used to hold babies in an upright position while in the bathtub. Some parents use baby bath seats or rings to free up their hands while washing a child. This occurs as suction cups fasten the seat or ring to the bottom of the tub, holding the baby in a stable position in the water. Some of these seats or rings may have an arm that attaches to the side of the bathtub to keep the baby’s seat in place.
