The high chair apparatus focuses on safety by providing no sharp edges. External edges and features of the apparatus are rounded to avoid potential injury to a child, whether in or around the apparatus. The seat prevents a child's escape from the chair via the harness and the divider. The built-in vacuum has a substantially selectively hidden hose so that the hose is out of the way except during use. The hose extends sufficiently to clean the apparatus and any area around the apparatus. The removable tray cover and chair back cover further aid in cleanup by providing removable washability. The pedestal housing the vacuum components is insulated to negate excessive noise. Triangularly positioned wheels provide mobility.
