7-position footrest included
Need another reason to get your kid excited about a car seat? The removable footrest has 7 positions that adjust to keep your child’s growing legs comfortably stabilized so they don’t dangle over the edge of the seat. Not only is it comfortable for your kiddo to rest their legs, but it also helps promote an upright posture.
rigid LATCH
Getting the bay™ latch SI installed is simple, thanks to the built-in rigid LATCH connectors and easy-to-read colored indicators that click right onto your car’s anchor points. Just extend the lower anchors, snap them in, push the seat back, and attach the tether. It’s so simple, you’ll feel like a pro from the start.
from toddler to pre-teen
Your stubborn toddler to ‘too-cool’ pre-teen won’t argue with you about getting in this seat. From the 4-position adjustable seat depth that gives them more room as they grow, to the plush harness and armrests, every detail is designed to keep your child comfy as they grow. The ventilated seatback helps them stay cool, while the 15-position headrest makes it easy to get the perfect fit for every ride.
3-in-1 car seat
This combination car seat features three modes that adapt along with your child, keeping them seated safely and comfortably as they grow. Bay latch SI starts as a forward-facing harnessed car seat, then transitions to a highback booster and finally a backless booster – three seats in one!
