When the time is right, the Maxi-Cosi Lila Modular Stroller easily switches from a single to duo stroller by adding either a Mico infant car seat or second seat. The included stroller adapters with the Duo Seat Kit allow for various riding configurations, accommodating both baby and toddler in a single stroller. It’s an essential addition for your growing family. Add a second seat and travel together in style on every journey.
