The Sonus 65™ Convertible Car Seat converts from a rear-facing car seat to a forward-facing seat as your child grows from infant to toddler. Evenflo® recommends that parents utilize the rear-facing option for as long as possible. With this in mind, the Sonus 65™ Convertible Car Seat features a rear-facing weight rating of up to 40 pounds and a forward-facing weight rating of up to 65 pounds. There are also 6 shoulder harness positions to achieve a true extended fit option.
