The Safety 1st Grow and Go™ All-in-One Comfort Cool Convertible Car Seat is built to grow and provide your child with superior protection every step of the way! It gives your child a safer and more comfortable ride from 5 to 100 lbs. and can be used in rear-facing, forward-facing, and belt-positioning booster mode. Fits children through 3 stages: rear-facing (5–40 lbs., 19"–40"), forward-facing (30–65 lbs., 34.4"–49"), and belt-positioning booster (40–100 lbs., 43.4"–52").Keep baby content in the car with the Grow and Go™ Comfort Cool Convertible Car Seat. The Comfort Cool fabric technology on the inserts and covers can be customized depending on the weather. One side is plush to keep baby warm and cozy, and the other side keeps baby cool and dry. Wicking fabrics pull moisture away from baby’s skin for quicker evaporation, while the cooling aspect increases airflow and breathability. Additionally, the car seat features three cozy reversible pillows for a snug fit that remove easily as your baby grows.In forward-facing mode, it protects your child in a harness up to 65 pounds. In both rear and forward-facing mode, harness holders keep the harness out of the way, so it’s easy to get your child in and out of the seat. The QuickFit™ Harness also lets you adjust the height of the headrest and harness with one hand, in one easy step. When your child is ready to use the vehicle seat belts, remove the harness for belt-positioning booster mode, suitable from 40-100 lbs. Buckling up with the vehicle belt is easy with the clearly visible red belt path guiding the way.This convertible car seat is also simple to clean with a machine washable and dryer safe cover that removes easily from the seat. The cover attaches with snaps so there’s no need to remove the harness or car seat. Just unsnap and lift the pad away to put it in the machine.You’ll appreciate the safer ride it gives your child and the extra space it leaves for you. And your child will enjoy a more comfortable ride.
