The Grow and Go Sprint All-in-One Convertible Car Seat has multiple comfort adjustment options to fit kids from birth to 10 years in three modes of use: rear-facing (5–40 lbs. 19 –40 ) forward-facing (22–65 lbs. 29 –49 ) and belt-positioning booster (40–100 lbs. 43 –52 ). As your little one grows the QuickFit™ harness lets you adjust the headrest and harness with one hand in one quick motion. No re-threading. No re-installing. In forward-facing mode our seat has two position options to get the best possible fit in your vehicle. The seat pad is made with antimicrobial fabric to inhibit the growth of bacteria and odor-causing microbes. When flailing arms and legs make it hard to get kids in and out of the seat our harness holders keep straps out of the way. And since messes are bound to happen the machine-washable and dryer-safe seat pad removes smoothly for easy cleaning. Safety 1st believes parenting should have fewer worries and more joyful moments. As the first and only leader in child safety Safety 1st is here to give you peace of mind so you can spend less time worrying and more time enjoying every first you experience with your child.
