Chicco KeyFit Max Infant Car Seat Base - Stay-in-Car Base

Our review of the Chicco KeyFit Max Infant Car Seat Base finds it ideal for parents who need a second, stay-in-car base for easy vehicle-to-vehicle transfers. The single biggest reason to buy is its combination of intuitive click-in compatibility with all Chicco KeyFit infant seats and the SuperCinch LATCH tightener that makes achieving a secure installation noticeably easier. For caregivers who value straightforward installation, extended rear-facing legroom and an anti-rebound bar for added stability, this base answers those needs without fuss.

Key Features

• Stay-in-car convenience: The base lets families keep an extra base installed so the infant car seat can be transferred between vehicles quickly and securely.
• Wide compatibility: Works with Chicco KeyFit, KeyFit 30, KeyFit 35 and KeyFit Max infant seats so one base suits multiple carriers from the same line.
• SuperCinch LATCH tightener: The force-multiplying tightener helps achieve a tight, secure fit with much less effort than manual tightening.
• Anti-rebound bar and extra legroom: Integrated anti-rebound bar adds stability and provides more rear-facing legroom to maximize safe rear-facing use.
• ReclineSure leveling system: One-hand, spring-loaded leveling foot used with RideRight bubble indicators verifies correct angle for safer installation.
• Vehicle seat protection: A smooth underside design helps protect the vehicle seat finish when the base is installed or removed.

Who It's For

Parents who regularly switch an infant seat between a primary vehicle and a second vehicle will appreciate the convenience of a stay-in-car base; it saves time and reduces installer error. Caregivers who already own a Chicco KeyFit series infant seat and want an exact compatible base will find this a natural fit.

Those who need a complete infant seat system should remember this listing is just a base and not a complete car seat; if you need the carrier included, look for the full infant seat package. Families with non-Chicco infant seats should check compatibility, as this base is intended for Chicco KeyFit models.
