Sixteen configurations come out of this one frame, which is why it suits a two-child household: one child eats in the high chair while the other spins in the activity center on a 10-in rotating seat. The tabletop detaches and flips, smooth on one face for painting and crafts, grooved on the other to hold building blocks. Height and tray each set to 3 levels, and two included straps turn the seat into a booster on a kitchen chair. A 5-point harness and anti-falling baffle meet ASTM and CPSIA at 44 lb, the BPA-free tray is dishwasher safe, and it assembles without tools.
