The True Fit Convertible Car Seat can be used from birth right on through to when your child is 65 lbs. The True Fit adapts better and easier to more cars than any other convertible car seat, and offers the comfort and safety features you have come to expect from Compass car seats, Compass booster seats and The First Years travel gear products. It offers deep side wings that have been side-impact tested, a full EPS foam liner that absorbs energy, and built-in lock offs to provide a secure installation without the use of confusing locking clips.
