Rule number one of happy parenting: never disturb a sleeping baby. These Joolz Hub2 car seat adapters give you the flexibility to hop out of your car and into a café, while your baby dreams the day away in undisturbed comfort. ​Just attach the adapters to your stroller chassis to turn your Joolz Hub2 into a travel system that works with almost any car seat. Now you can quickly and easily transfer the whole car seat, including your snoozing baby, out of the car and onto your stroller. Just click your car seat onto your stroller, and off you go.​
