Main Highlights

Our original SlimFit convertible car seat has been adapted to meet the EU’s new R129 standards. Most importantly, SlimFit R129 has undergone more extensive side impact testing and ensures your little one stays rearward facing for longer.
2-in-1 convertible car seat, SlimFit R129 easily transitions from a rearward-facing harnessed seat (40-105cm) to a forward-facing highback booster (100-145cm) to adapt as your child grows from baby to big kid.
Interchangeable TrueShield side impact protection pod attaches to either side of the car seat. In the event of a collision, it works to reduce the impact and better protects your child from head to hips.
Adjustable width, SlimFit R129 adapts as your child grows both up and out. When the headrest is raised, the side wings of the car seat simultaneously expand, keeping your little one comfortable and safe for as long as they ride in this convertible car seat.
6-position recline, with 2 rearward and 4 forward recline positions, your child will enjoy the ultimate in comfort on each and every ride.
