Overview
The Infantino 203-004 is a portable seat rated for babies up to 33 pounds, built from foam and plastic rather than the metal-frame construction of a full-size highchair.
Category label says highchair, but a 33 pound weight limit and a portable design point to a compact seat meant to travel or clip onto a dining chair rather than stand alone at a table. Buyers should read it as a lightweight, go-anywhere seat, not a replacement for a full kitchen highchair with a tray and adjustable legs.
- 33 pound weight capacity
- Foam and plastic construction
- Portable design
Who it's for
Parents who want a seat to carry to grandma's house, a restaurant, or a small kitchen where a full highchair will not fit. Families needing a seat for a child heavier than 33 pounds should look elsewhere.
Pros and cons
- Portable design travels easily
- Lightweight foam and plastic construction
- 33 pound weight capacity limits how long a child can use it
- Not a full stand-alone highchair
Performance notes
The foam and plastic build keeps the seat light enough to carry, and the 33 pound weight capacity places it firmly in the infant to young toddler range rather than covering a child through the preschool years.
