Stokke Clikk High Chair

The Clikk is the middle ground between IKEA's bare basics and the big convertible chairs. Its surfaces are smooth from top to bottom, the tray goes in the dishwasher, and the harness comes off for the washing machine, so after-dinner cleanup is a wipe and a load. It clicks together without tools and has an adjustable footrest. The limit is age: it is designed for roughly 6 months to 3 years, up to 33 pounds, so it covers weaning and the toddler years rather than growing into a school-age chair.
