Our verdict

An all-in-one seat with built-in cooling fans that runs from newborn to booster for hot climates and sweaty kids. It is large and fan dependent on car power, so check the fit in smaller cars.

Overview

Maxi-Cosi built the Pria Chill as an all-in-one convertible car seat with VentMax, a fan system that blows air through open-cell padding and mesh on warm days. It works rear-facing, forward-facing, then as a belt-positioning booster.

Cooling fans that switch on as temperature rises make hot summer drives easier on kids. The seat is big, so smaller back seats may struggle with rear-facing fit.

Who it's for

Kids who arrive sweaty after car rides gain the most from the fans and mesh. Those who need a light, portable seat for frequent moves should look at a travel seat.

Pros and cons

Pros
  • Built-in cooling fans
  • Three modes from newborn to booster
  • No-rethread harness adjustment
  • Magnetic chest clip
Cons
  • Fans need car power
  • Seat weight not listed

Performance notes

Fans pull air through open-cell padding, and sensors switch them on when it warms up, with an indicator light. QuikFit moves headrest and harness together so fit tracks growth without rethreading. Recline positions help get the right angle in different vehicles.
