Overview
The Costzon BB4640 is a stationary highchair rated for babies up to 40 pounds, measuring 21 by 26 by 36 inches and weighing about 8.7 kilograms, roughly 19 pounds, itself.
At about 19 pounds it is heavier than a fold-flat travel highchair, and the listing marks it as not portable, so this reads as a chair meant to stay put in the kitchen or dining area rather than one you fold away or take on trips.
- 40 lb weight capacity
- 21 x 26 x 36 inch footprint
- 8.7 kg item weight
- Non-portable, stationary design
Who it's for
Households wanting a stationary highchair for daily use at home, up to the 40 pound limit. Not suited to anyone wanting a lightweight, foldable or travel highchair.
Pros and cons
- 40 pound weight capacity covers most of the highchair years
- Sturdy stationary build
- Not portable, no fold-flat option
- At 8.7 kg, heavier to move between rooms than a travel chair
Performance notes
With a fixed, non-folding build and nearly 19 pounds of its own weight, the chair trades portability for a sturdier stationary base at the dining table.
