The Safety 1st Smooth Ride Convertible Car Seat can be used as a rear-facing infant car seat from 5–40 lbs. and as a forward-facing car seat for toddlers from 30–50 lbs. The 5-point harness, with covers for comfort, easily adjusts from the front of the seat and features 5 heights and 3 buckle locations to help you get the best fit for your growing little one. This 2-in-1 car seat fits 3 across the back seat of most vehicles, thanks to its slim design. For added convenience, the cup holder is removable and dishwasher-safe. Plus, the seat pad is machine-washable and dryer-safe, so you can quickly clean up messes. It's certified for use on an aircraft, and the lightweight, compact design makes it easy to get to your destination—making this a perfect portable travel car seat. Actual fit may vary. Not all children will comfortably fit in the seat for the full weight and height ranges listed.
