With these Sunny adapters, the Hauck infant car seats iPro Baby (i-Size) and Comfort Fix (Stiftung Warentest: Test rating good) can be combined with the Sunny stroller. The adapters are simply attached to the buggy chassis, and the Hauck infant car seat is secured on top. This creates a practical shop-and-drive system, allowing parents to conveniently run short errands or navigate through narrow stores.
