Four of the sixteen setups matter most as a child grows: a floor chair with a 12-in seat for a 6-month-old just sitting up, a full high chair at the table, a strap-on booster for a regular kitchen chair, and an activity center for play. The waterproof cushion wipes down with a damp cloth instead of going through a wash cycle, and the BPA-free tray goes in the dishwasher. Height and tray each adjust to 3 levels. A 5-point harness with an anti-falling baffle handles 44 lb under ASTM and CPSIA. No tools needed to build it.
