In Stage 2, the Fit2 Adapt easily transitions into a rear-facing toddler car seat, offering a more upright seating position for toddlers from 9 to 24 months – without taking up extra space in the vehicle. A 7-position headrest and padded no-rethread harness provide adjustability to accommodate growth throughout both stages.The car seat carrier clicks effortlessly into the included-stay-in-car, 2-position base and compatible Chicco strollers, creating a convenient car seat and stroller combo.Fit2 Adapt baby car seat features patented 37.5 Technology to draw away moisture and help maintain an ideal core body temperature. This innovative, humidity-regulating fabric is permanently embedded with naturally derived volcanic mineral particles to regulate your child’s microclimate – speeding evaporation to help cool or returning the body’s own infrared energy to help warm.For an ideal newborn car seat, the removable head and body support for newborns and smaller infants features reversible knit/mesh fabrics for all-season comfort.The Fit2 Adapt includes ReclineSure spring-loaded leveling foot that works in tandem with RideRight bubble levels to easily verify and achieve proper base angle during installation.

The base is also designed with easy belt routing and integrated lock-offs for alternate installation with the vehicle seat belt.
