Joie Stages R44 from Birth Combination Group 0+1/2 Belted Car Seat (Birth - Approx. 7 Years, 0-25kg) - Coal
Why we love it
Grows with your child.
Simple to install.
Highly adjustable for comfort.
Main highlights
STEEL REINFORCED SHELL, bound to protect. Steel frame support keeps car seat strong during impact, extends the life of the materials of the seat to 10 years, and adds weight to keep the seat tight and low to the vehicle seat for better stability and protection.
SEATBELT INSTALL, simple security. The stages convertible car seat attaches securely to the seat with a seatbelt , making it ideal for older model vehicles that don't have ISOFIX or compact vehicles.
GROW TOGETHER, designed with growth in mind. Multi-height headrest and harness system that adjusts simultaneously with just one hand… even while the car seat is installed, and without rethreading a harness. It’s just what you need to be prepared for those growth spurts that seem to happen overnight.
BIRTH TO 7 YEARS, built to grow with little ones. Get through years of growth in a single seat for birth to 7 years. It offers rear facing use up to 18 kg, forward facing use with a harness from 9-18 kg, and forward facing as a belted booster from 15-25 kg.
4 RECLINE OPTIONS for laidback riding. 1 recline position while rear facing and 3 when forward facing means you’ll always have options to help you customise their comfort.
