The MeToo Navy Clip-On High Chair from Phil & Teds is surely the world's smallest folding high chair. With flat packing portability (the perfect on-the-go feed companion for a Phil & Teds Inline Buggy), the MeToo is ideal for children sitting up on their own, and is super lightweight! It features washable fabric for fuss-free care and hygienic feeding, a four-point safety harness and crotch restraint and an aluminum frame. Clamp diameter for most any bench or tabletop is 0.7 to 2" deep. Holds children up to 37 pounds.
