Six configurations share one frame so this 6-in-1 convertible high chair works as a full-size high chair, booster seat, child stool, and kids table and chair as your baby grows from 6-36 months. The 23 x 23 x 38.5 in setup uses a pyramid structure with non-slip foot pads, safety harness, and anti-falling barrier to help keep children secure up to 55 lbs. A 3-position adjustable tray lets you set the eating distance and remove it completely for play, while the double layer seat cushion and removable, dishwasher safe tray surface simplify mealtime comfort and cleanup.
