A forward-facing child restraint (C-E) positions a
child upright to face forward in the vehicle. These
forward-facing restraints are designed to help
protect children who are from 20 to 40 lbs.
(9 to 18 kg) and about 26 to 40 inches (66 to
102 cm) in height, or up to around four years of
age. One type, a convertible restraint, is designed to
be used either as a rear-facing infant seat or
a
forward-facing child seat.
