Here you have complete stroller set, consisting of a Joolz pram with a baby carry cot.
In the 3-in-1 kits are available then the matching infant car seat, such as a Maxi Cosi infant car seat or the Cybex Aton 5 car seat.
The 3-in-1 sets are useful, because your baby in the infant car seat can be simply clicked onto the frame for short distances using the supplied adapters. This is ideal if you have short distances to see a doctor, or make a small purchase. So your baby can always lie in the infant car seat.
