6-position recline, with 2 rearward and 4 forward recline positions, your child will enjoy the ultimate in comfort on each and every ride.
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.
