The Safety 1st Grow and Go™ ARB AIR 3-in-1 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 with extended use at each stage; including up to 40 pounds in the rear-facing position. From infant through growing toddler, you’ll be giving your child superior Side Impact protection with Air Protect. When compared to similar car seats without Air Protect, testing proves that seats with Air Protect are safer. In fact, the advanced cushioning system, developed with superior safety testing that exceeds government standards, makes this one of our safest seats on the market.|Rear-facing, the padded Anti-Rebound Bar adds an extra measure of safety by preventing the car seat from over-rotating in the event of a sudden stop or crash. In forward-facing mode, Grow and Go ARB protects your child in a harness up to 65 pounds. The QuickFit™ Harness lets you adjust the height of the headrest and harness, in one easy step. It’s easy to get your child in and out of the seat, built-in harness holders keep the harness straps out of the way! 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 belt path guiding the way.|The seat is a snap 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.
