Add the Maxi-Cosi Coral XP infant car seat base to your family's second car, so you’re ready to travel whenever you need to. The Coral XP infant car seat extra base is adjustable to ensure a proper fit in your vehicle, with a self-retracting one-click UAS system for easy installation. An improved safety feature is the anti-rotation stability leg that limits back and forth movement for maximum head and neck protection. The red-to-green tightness indicators provide visual confirmation of accurate installation, whether using vehicle belt or UAS installation. The base also features an integrated belt lockoff for easy and secure seat belt installation. With an additional base, there’s no need to slow down for re-installation of the base when you want to go out. Just attach your car seat and be on your way.
