Maxi-Cosi Pria™ Chill All-in-One Convertible Car Seat

Meet the coolest car seat in town, the new Pria Chill with VentMax technology. 

The first-of-its-kind Pria Chill will help keep your little one comfy in their car seat. VentMax is an integrated automatic fan system with specially designed sensors that engage fans to circulate air when the temperature rises.

Special open-cell padding and soft, breathable mesh fabric allow air to circulate around your child (2 fans in the lumbar area, 1 in the headrest) to enhance airflow and comfort. You’ll know the VentMax fans are engaged when you see the automatic indicator light. The VentMax system is also water resistant (don’t worry about spills!), super quiet, and shuts off when the car power port does.

Our innovative all-in-one convertible car seat will be part of your family for years in 3 modes of use: rear-facing (4–40 lbs. and 19"–40"), forward-facing (22–65 lbs. and 29"–49"), and belt-positioning booster (40–100 lbs. and 43"–52"). Pria Chill also features soft, premium PureCosiTM fabrics, QuikFit for easy harness and headrest adjustments, and removable infant support pillows to keep little ones secure and comfy. Easy in-and-out harness holders keep straps from getting in the way when you put your little one in the car seat and take them out, and the ClipQuik™ Magnetic Chest Clip promotes struggle-free buckling.
