Six seating modes share one PP and PU fabric frame so you can switch from a full high chair to a booster seat, child stool, or kids table and chair as your baby grows. The 23 x 23 x 38.5 in overall size creates a stable pyramid structure that helps keep the chair steady during meals and play. Non-slip foot pads, a safety harness and an anti-falling barrier work together to help secure children up to 55 lbs. A 3-position adjustable tray adapts to your child’s changing size and activity needs. The double-layer seat cushion supports comfortable sitting, and both the tray and cushion are removable so you can wipe surfaces or place the tray in the dishwasher for cleaning.
