10.4 Backrest depth
The backrest depth is adjusted by
depressing the popper then sliding the back
support tube to the desired position. This is
very important as it will ensure the seat will fit
the child, both when they are upright and
in a recline position.
There are three settings where the popper
can be located.

We recommend that you measure the child's
upper leg length to define the required seat
depth (SD). To do this measure from the
child's lower back to the back of their knee.
Then set the backrest to position A, B or C
based on the table below.
This backrest depth should not
be adjusted while the child is in the
seating system.
