The Maxi-Cosi Mico Infant Car Seat Base, compatible with all Mico infant car seats, is an essential addition to your family's second car, ensuring you're always ready to travel. This adjustable base guarantees a proper fit in your vehicle and features a self-retracting one-click UAS system for easy installation. Enhanced safety is provided by the anti-rotation stability leg, which limits back and forth movement for maximum head and neck protection. Red-to-green tightness indicators offer visual confirmation of accurate installation, whether using a vehicle belt or UAS system. The integrated belt lockoff ensures a secure and straightforward seat belt installation. With an additional base, there's no need to slow down for re-installation when you want to go out—just attach your car seat and be on your way.
