Quick and quiet transfers. Nothing is more satisfying than successfully transferring a sleeping baby without waking them up! You can keep your baby in the car seat and switch quickly and quietly from car to stroller and back again. Just click on the adapters and your car seat easily fits onto the Joolz Geo³’s lower position. Please note: if you want to add a second car seat to your Joolz Geo, you’ll also need a set of upper adapters.
