A travel system combines a pram with an infant carrier/capsule to enable easy transition of your baby from your car to your pram. This makes life a whole lot more simple as there is no waking baby whilst trying to peel his arms out of the straps of a car seat. Travel systems can cater for one or two children depending on the pram you use. These travel systems are ideal for a small baby and toddler or twins. Most prams require adaptors that allow the capsule to sit within the pram frame, however some do not require this.
