Our travel systems for babies are 3 in 1 sets. That means they come with pram including a carrycot for newborns which will later convert into a pushchair and a baby car seat.
With the travel system you will also get the adapter to attach the baby car seat to the stroller chassis. It makes the transition form A to B with your baby in the car seat a lot easier and can be used for example while shopping or when you have to cover short distances. For long walks we recommend to use the carrycot where your baby can lay flat.
