A high chair incorporates a swivel feature and a height adjustment feature that permits the seat member to be positioned to the convenience of the caregiver. The high chair includes an H-shaped base member having a vertical pedestal member that houses a gas cylinder that provides height adjustment for the seat member and that supports the seat member for rotational movement relative to the pedestal. The H-shaped base allows the high chair to be positioned close to the caregiver. A swivel lock includes an actuation lever that has handles positioned on opposing sides of the seat member for actuation from either side of the high chair. The pivoted actuation lever also includes a spring-loaded stop member that is engagable with a toothed gear plate affixed to the pedestal to secure the rotated position of the seat member by positioning the stop member between teeth on the gear plate.
