This adapter allows you to fit your Graco car seat on the Bugaboo Cameleon or Frog stroller chassis, so that transitioning from car to stroller is a breeze. The snap-and-go frame makes it so simple, you won't even have to wake your baby (though the adapter must be removed to collapse the stroller chassis). We're big fans of the multi-stage, innovative, very easy-to-use Bugaboo.
