Six configurations let this convertible baby high chair work as a full-size high chair, booster seat, child stool, or kids table and chair set, so one frame supports feeding and play from 6 to 36 months. The 23 x 23 x 38.5 in overall size provides a stable pyramid structure with non-slip foot pads. A 3-position adjustable tray and 55-lb weight capacity adapt as your child grows. The BPA-free PP tray is dishwasher safe, and the removable double-layer PU fabric seat cushion offers a comfortable, easy-to-clean surface. A safety harness and anti-falling barrier help keep little ones secure during meals.
