In updating one of the most popular car seats on the market, the UPPAbaby Mesa V2 car seat is better than ever. Easy to install and enhanced with numerous safety features, its intuitive design allows parents to use the carrier with confidence. A streamlined, low-profile base connects to vehicle seat in minutes through a simple-to-use retracting LATCH system and indicator window to confirm correct installation. Secure baby in the grey car seat, lock the carrier into place, and you're ready to ride. Protective features include side impact protection, a larger adjustable headrest, and no-rethread harness that adjusts as the child grows. It's a good fit for baby too: an integrated, larger canopy shields little faces from the sun, while the newly updated infant insert cradles newborns as small as 4 pounds. Take it from the car to the Uppababy Vista or Cruz stroller (sold separately) for a car-to-sidewalk transition that's as convenient as the rest of the car seat experience.
