The tray is where this folding high chair earns its keep: high-grade BPA-free plastic that handles hot food without warping and goes straight onto the dishwasher rack. Behind it, the backrest and footrest each set to multiple positions, so a 6-month-old gets support and a 3-year-old gets legroom. The frame itself adjusts from 36 in to 43.5 in tall and folds down to 16 in wide, narrow enough to stand between a fridge and a wall. Cushions come off for cleaning and shed cooking oil. Rated 33 lb on a 20-lb chair.
