Your child should use the built-in harness if:
child weighs from
20 to
40 lbs.
(9 to 18 kg), and
is between
27 and 40
inches
(69 and 102 cm)
in height, and
child is at least
one year
old
and can sit upright
unassisted, and
child’s shoulders are
below
top harness slots.
If shoulders are above
top harness slots, child is
too large for built-in harness. You
must
remove
the harness and use the booster seat with your
vehicle’s lap and shoulder belt system.

as it is suitable and comfortable for your child.
