Rule number one for happy parents: never wake a sleeping baby. These Joolz car seat adapters give you the flexibility to get out of the car and into a coffee shop, while your baby continues to dream undisturbed. Combine your Joolz Aer with almost any car seat by attaching the adapters to the chassis of your Joolz buggy. Quickly and easily click the car seat, including your dozing baby, onto your stroller and you're ready to go.
